Hi,
I have the same issue, with 176MB capx. Followed the save as project (folder)... than when I try to open the caproj I've got this error message:
---------------------------

Check failure! This is probably a bug:
Cannot find project file for animation frame
File: H:\Google Drive\Projects\Tales4Fun\Game\BookInteracrive\BookSimple104R100\Animations\AlpineCroco1\Default\000.png
This can indicate project corruption - you may be able to retry/ignore these messages and replace missing images in the project. However, please report this issue to Scirra with the steps you were doing immediately before this problem occurred.

I've checked the Animations folder, it have the dir structure, but not any image is inside in, the size is zero. I use R100.
