I'm mobile user. I use Sony Xperia Z3 Compact. Game ran well, I could run big planes that are more than 500 parts, less than 600.Now, I tried some not so big airliners (250-380 parts) and it ran at like 17-20 FPS(
Now i tried to build another plane, with all new stuff in it, and parts copied themselves for no reason! (pressed undo button - part
copied itself).
So, devs added new big bugs and messed up optimization. Need another update that fixes it all
