Note to self: the problem is connected to the changes from Issue 25, which I think are correct.
ADOM 1.2.0 prints "You really feel satiated now" if you continue eating stuff and your satiation level rises from "satiated" to "bloated". I think this didn't happen with ADOM 1.1.1 (need to verify this).
EDIT: further debugging shows that the satiation level is correct. If the PC gets bloated, the status line indicates this immediately by showing the "Bloated" status. The bug is that the message "you really feel satiated now." is only printed _after_ the next action of the PC. This never happened with ADOM 1.1.1 because the message wasn't printed with that version due to wrong satiation level change detection.
