OK they went the hard way. Now if you have selected a troop card all special gem animations gets boosted so it’s impossible to reproduce the way I recorded it.
But in case if you DONT hold a troop card, animation use default (slow) speed. THEN you can select a the card and cause softlock. They didn’t fix the bug, they made its less likely to appear, yet I managed to get stuck at it yesterday.
Overall I understand the rush to release the content instead of a patch, so this workaround kinda plausible, but the team needs to remember these bugs still there, technical debt increases.
