@Michał Wieczorek (michal1000w) Hi! Was just trying out the file but didn't get a crash so far.

It might be because I just recently committed a bigger fix (rB1a5b988509fa). Can you try again with a daily build (

Yes, after some tests it seems to be fixed :D
Thank you for your work and have a nice day

Ok great, thanks for testing! Similar to T84649 the update then fixed this crash too. Cheers!
