Don't know if my problem should be considered a (apparent) bug, so for the moment I'm posting here a brief description.
I've been working on this project (a sort of puzzle/checkerboard game) a long time (with several interruptions) - it was created in C2, then migrated to C3 without any problem. I'm using C3 desktop, then I export via C2 engine as a Cordova file, then build the apk via Cordova CLI.
The project relies on the Rex_Rainbow "Grid" series, a bunch of plugins related to management of chess on a square grid, that were migrated to C3 by Rex itself and were perfectly working (until R120).
Well, in the first apk build after the R120 update, suddenly the movement, the coordinates, the behavior etc of some type of chess became completely and absurdely wrong and unmanageable. Note that on R111 everything were working perfectly, and few minutes ago I build the apk via the "old" R111 (online) and now everything works correctly again.
Did anyone have the same problem?
Of course for my next projects I will NOT use external plugins anymore (in order to use the new C3 engine), but for the moment I need to finish this one without rewriting dozens of complicated events (it's almost over, I'm planning to publish it in a couple of month).
My only chance is to use R111 online?
