Okay so I didn't really know whether to put this in general discussion or in bug reports, please move this if it's not in the appropriate spot now.
As I was browsing through the recent changes in Trac, I noticed changeset 6170. Added line 830 says
TERGET_BEHIND_VICTIM = 65, // uses in teleport behind spells
I guess it's a typo and it should be TARGET.
Could be trivial, could be the cause of confusion later on. either way, since the search indicates nobody else mentioned it I felt compelled to do so.
Cheers, keep up the good work
