Hello!

Thanks for your report. This is the first time we have heard of this strange behaviour.
We've been told of instances where the game could act weirdly after a long PC uptime (usually days). A simple restart of the PC was all it took to make Chonkers run properly.
If that's not your case, we'd gladly examine your save file and verify there's no corruption.

You can find the save folder, on Windows:
On Linux:

Please send us save_data.dat and save_data_backup.dat here via cloud link or to our email.

Thanks!

Thanks, I will send an email.
