Upgraded from ADOM II 0.2.3 to 0.2.5 on OSX (happens on Windows 7 too). Chose "ADOM classic" keybindings (see http://www.adom.de/forums/project.php?issueid=967). Whenever I try to save, either by using "Save Game" from the menu or by pressing SHIFT+S, the following exception occurs.
Fixed for ADOM II 0.2.6. Please send your real name to creator(at)ancientdomainsofmystery.com for it to be included in the credits. (If you were already asked to do so you can ignore this message. Please include a reference to the bug or RFE you are credited for.)
