The Tavern

Potion of experience seems buggy to say the least on this version. There are two effects to quaffing the potion

1. This has only happened twice, but quaffing it levels me up to 27, regardless of my level previous to quaffing

2. The game crashes and I can resume playing from a previous saved point (usually from when I first entered the floor). This happens much more often.

Anyone else seem to have this issue? Did it get fixed in a later version?

This is a known problem due to the OSX compiler, see this Mantis ticket for more information and possible workarounds: https://crawl.develz.org/mantis/view.php?id=6661
