I just had an issue where I was simply de-grouping and un-welding some objects and the game froze.... I lost like 20min. Also, had a glitch where I selected 3 piece and created a group, and one of the object reset it's orientation... Very annoying! ... Just had it happen again, there are some groups that I cannot unweld without it freezing the game. --- Double Post Merged, Mar 3, 2016 --- Ps, these are not big groups either I'm talking no more than 10 pieces, and it crashes upon un-welding.
Is this something where you can hop into a brand new canvas and get it to happen? Is it easily reproducible?
Not tested, this is circumstantial evidence based on a map that was built pre-patch, and the edited post patch, by copying an existing group and then not being able to unweld / ungroup.
Pss: from reading other posts some of this may be attributed to group color changing. I realized there are a few factors relevant to this glitch, hard to pinpoint exactly, hope this helps.
