ALTER_TLK is only used in Qwinn's PST stuff (that I know of).
Oh. Who cares then :D.
V211.04 throws a LAUNCH_MACRO_ACTION "tb#tutu_weaponprof" error in line 6292 in BG2 Tweaks (v6 on my install). Not sure how it got away with this in the first place - I thought it was LAUNCH_ACTION_MACRO. What's more, it's your prefix there. But I don't know why it was trying to parse that tp2 anyway since I wasn't installing or uninstalling it and it's installed before the mod I'm messing with.
Other than that, the BWP stress-test went well enough. There are still a few dialogues that take a while to mess with (berrun, dynaj, jaheiraj and tb#lotr) but I suspect it's our own code and the dialogues themselves rather than WeiDU. Anyway, there's no duplicate entries in the DEBUG now and ~20 seconds per dialogue is a damn sight better than ~5 minutes.
No ETA.
Not even a rough guess? Let me put it this way then - what's holding you back at present from a new version?
