I don’t know if this is a software or hardware thing, but lately the SimplePlanes app would crash in the designer or in the world. The part count seems to be the only somewhat consistent factor with problem aircraft usually being 300-400+ parts. Which is weird considering my device can usually run ~1000 parts no problem. This issue somewhat extends to SimpleRockets 2 so this makes me think it’s a hardware issue but I’m sure how I can fix it. My device as usual is an iPod Touch 7th Generation running iOS 14.7.1.
