Well that's a lot of bugs. Good job finding and posting all of them.
Fixed the drunken bug, but it's a placeholder fix. The entire section with combat calculations is a huge mess and I will have to remake it from ground up one day. The crash happened in rare case only when you missed / glanced an attack so for now, you will do 1 damage instead of crashing.
Speedpotion double use was fixed.
Shield had indeed wrong weapon type asigned. I changed them to blunt.
Starting weapon perk bonus has been adjusted.
Fast travel combat crash is something that I think is a quirk of the engine. I had similiar crashes, when the game just hangs when you turn it on and throws some kind of error. This happens like twice a year to me though. Battles taking place after teleporting has the same roots I think. I tried to fix it and I think it worked, but I think it can still happen if you are very, very precise with the timing.
The entire kobold den section is horribly outdated and I will be redoing it once I put the faction system in the game. For now though, I just disabled escaping from these encounters.
Most cutscenes don't happen unless you are alone. They don't have any time limits so you will see them eventualy. This was done simply because adding all dialogue for different combinations of party members you can have would drive me mad.
Alcogone removed the drunk negatives partialy. You can drink again and NPCs don't think you are drunk anymore, but the state still remained on you. I fixed that.
Crafting points at 0 is intentional. Skipping the start puts you at your tent and refusing the tutorial. Doing the tutorial moves you one week forward. That's why your crafting points were filled.
Both chat options for Helena and George have been fixed.
Those dialogue options like "Billy" or "Suong" are not working properly. Most of them have no text or the way you get them is way too obtuse. If I remember correcly, you can get the "Suong" topic by reading the post next to Billy's door when he is visiting her. No NPC will tell you anything about that topic anyway, except maybe the bridge guard.
Again, thanks for all those reports. I will upload new version in about an hour.
