Someone reported a bug about the Upgrade screen becoming unavailable after a first or second upgrade has been bought, and also possibly the disabling of Experience gain after a first boss has been defeated.
I've been unable to recreate those bugs with both versions of the available downloads: all works fine for me. Therefore I'd like to request anyone's help in trying to recreate those bugs, please. This should only take you 15-25 minutes.
By the way I've also noticed that I forgot to delete the save files and to apply Cherry's Better AEP patch on the download that includes the RTP.
I'll fix that after the above bugs have been confirmed or refuted by one/many of you kind souls.
