I now cannot save my game, I keep getting "Save failed" and can't progress at the start of the next floor. This bug persists even if I start a new run. What a shame.
Yes, there is only so many saves/loads you can do before game cannot save anymore, and can even corrupt your last save like it happened to me when i loaded game with half of the inventory shown and being unable to do anything.
I was able to run new games though, no problem with progressing the floors normally. It just keep saying "Save failed" so I kinda have to do it in true roguelike style :D
