I submitted another update last night for Sea Assault and Ant Planet -- making sure they work in the new iOS 4 GM. I found a memory dealloc error which caused Sea Assault to crash on start up in iOS 4 GM. Ant Planet was not crashing yet had the same bug. Astroidica does not have this memory issue.
Typically, I wait till the last gm build to do these checks because I get afraid that I might brick my device with beta software. This approach worked well when 3.0 was released.
So, expect another round of updates for Sea Assault and Ant Planet. Usually, I wait a couple weeks at least between updates but this is an important fix. It would not surprise me, if it created an issue with iPad too.
