Graphical Bug ?

For those who might encounter the same issue :

We investigated the issue on the discord with Snickett (you will find the discussion in the "Technical assistance for MoA needed" Thread). It seems it is a kind of save corruption problem caused by a crash during an R&D purchase I made before (I probably messed a bit while saving and loading the game from the shop because I remember having a crash in the R&D so it might be wise to avoid doing so).

If you encounter the issue, one way of dealing with it would be to load the game prior to this crash and redo everything from that point. Also, you can do a clean reinstall of the game by deleting the game and the saves in AppData\Roaming\RenPy\Sunrider Episode 2 Save Data\ and reinstalling it (tested). (Perhaps only deleting the saves from the appdata location and the game location is enough (untested)).

(I don't know if can close the thread myself but if not, the admins could consider the issue as resolved since I restarted a new playthrough from a clean resinstall and it worked.)
