Part of image missing without me doing so.

[McFlystradamus]

Hello everyone,

I was in AP wanting to clip some art away from the background. I did almost make it perfect, except there is a portion that is missing which was never touched by me using any other tools. It seems to have unknowingly "erased" itself.
I read other forums and tried suggested solutions, but nothing worked. I don't want to have to do the selection all over since I am not very savvy with it.
The mistake can be found at the bottom of the plant inside the red circle.

I've uploaded the source file if anyone can take a look.

Hi,

no big deal. Just take a brush, select white color, and paint in the missing part to the mask layer again. Takes about 5 Seconds to correct.

But then i found several more imperfections. So you may need 10 600 more seconds to correct all of them.

Best practice advice: create a fill layer with a strong contrasting primary color (e.g. blue), an put it  on bottom in the layer stack, to see all the imperfections. It really depends on what do you intend to do with the masked image if this matters - or not.

Thanks for the tip.
I've tried this one before and the only thing that happens is adding white and essentially erasing my object. I've even watched videos on it and that hasn't worked for me before.
Is it an issue that the object is already masked?

It is the mask that is the issue..It is just not 100% accurate.. You just need to manually correct it...

1. Select the mask
2. Zoom in to area that is incorrect
3. Select paint brush and set colour to white and paint in area or black to erase

Ensure that the mask layer is selected, not the pixel layer.

A small portion of the pixel layer is already erased (independent from the mask). You may need to start with a fresh copy of the original image.

I noticed that a part of the image was already made transparent, obviously using a brush, and not done perfectly as portions are left partially transparent.

Other parts seem to be th result of "erase white paper", which erases all white areas, even by mistake those inside the plant.

You should consider using only one technique (but do not mix):

• using a mask (non-destructve, preferred)
• or erasing from the pixel layers (destructive, only for experienced users)

Never the less, getting to perfect masks is tedious and time consuming.

@NotMyFault

I am unable to select just the mask layer without the pixel layer. Is that normal?
 

In regards to the brushes used, I was only correcting the inside portions that were background only. Sadly, I didn’t discover the “erase background” brush until after I begun with using the “erase” brush. I can see the example you highlighted as my error, but the other areas seem to have vanished. 
I still cannot explain why there are two portions inside my mask that are missing from the mask. Both areas I didn’t use the brush around. 
I’m generally using “undo task” liberally and would have caught my error before advancing. 

Would it be possible to add the source image to the file again and some how “restore” the areas that are missing and erased?

Absolutely, just use File>place to put in the original image from a file as layer.

This happens even to most experienced users. Selecting the wrong layer during edits, selecting the wrong tool by accident are the most common errors. Thank god and Affinity for the undo / history function.

For future edits: you may add snapshots (frequently) to save any intermediate state, which can come handy as you can use the undo brush selectively restore from these snapshots. And do not forget to occasionally save the file (at least every 30 minutes).

If you mouse-click on the thumbnail image of the mask layer, it will be selected, and affected by edits.

If you mouse-click on the thumbnail image of the pixel layer, it will be selected, but all nested layers will be shown as selected. Nevre the less, only the pixel layer gets edited

@NotMyFault
I appreciate all the feedback.
I am still unable to get the results based on your advice.

Could you explain what I can do to restore the parts I want after I place image into the file? 

[NotMyFault]

move it in the position (in the layer stack) where the "damaged" image was. Deactivate the damaged layer. If stuck, could you upload the file again?
