Thanks for updating to v0.9a Histidine.
Currently running on RC10 with a WIP / dev version of LazyWizard's Console Commands (Commit #7009385 I believe?).
Invoking any of the Combat Chatter related commands (either SetChatterChar or PrintChatterChars <arg> causes an immediate CTD.
I don't have the full starsector.log, but the last I saw, it said something about those commands not existing?
Though again, that's probably due to me using a WIP / dev version of the console.
Typing help SetChatterChar or help PrintChatterChars still displays the relevant help instructions without crashing, however.
