Mask moving to random position on symbol

[PaulMakesGames]

Hello,

I've got multiple symbols where masks are being used to add texture but every so often I'll be working on another part of the document and the mask will move to a huge position far off screen which I then have to find and move back to the correct position. This keeps happening and I so far haven't found a way to reproduce it reliably. See below screenshots on what I mean.

Has anyone else had this issue and is there a way to fix it? If not can I log a bug?

 

What I start with:

 

What randomly happens:

 

 

Thanks for your help.

Hi PaulMakesGames and Welcome to the Forums,

Can't say i've ran into this issue before but if you could attach the .afdesign file, i'll see if i can get some steps to reproduce the issue

Hi Stokerg,

Thanks for the welcome. I can't seem to reproduce the issue anymore so maybe it was something I was doing or the recent update fixed it. I'll leave it for now and reply here if it happens again.

Thanks for your help.
