[1.0.50] Game stops as soon as I talk to a NPC [FIXED]

[Rabert]

1) I'm absolutely new to Kenshi, so maybe it's just simple ignorance how to operate the game. Do I need to do something different but to click on one of the options in the answer box of the dialogue windows?

2a) When I click on a NPC (for instance to hire one or to trade with one), the game stops and a two part dialogue box appears. The NPC asks something, I klick on my answer, nothing happens. All keyboard commands are ignored with the exception of the ESC-key. Mouse klicks do nothing, but I can still zoom in and out with the mouse-wheel and pan with moving the cursor to the edges. The only means to leave that situation is to exit the game or to load the last save from the ESC-window.
2b) The game seems to no longer save on exit. The save.log files notes: [Info] Creating temporary folder C:\Program Files (x86)\Steam\steamapps\common\Kenshi\save\/_current1/, but there is neither such a folder nor any save file at that location. All folders in kenshi\save are empty.
2c) I seem to not be able to mark several characters of my group with the mouse cursor, I have to klick at all of them individually at the GUI to get them act together.

3) What I tried so far:
-> reinstalling the game
-> starting a new game with a different starting point in a different town (so far Wanderer, Trader and Settlers)
-> trying different characters with the settlers group
-> talking to different NPCs
-> activating and deactivating mods
-> re-evaluating the files over the Steam app and trying the ingame F11 troubleshooting

4) Here are the requested files:
-> There is no crash dump in C:\Program Files (x86)\Steam\steamapps\common\Kenshi'
-> This is the last save file available: https://ufile.io/45vcq1wz (for some reason it is placed in C:\Users\xxx\AppData\Local\kenshi\save, not at the place as of 2b above)
-> kenshi log: https://ufile.io/vnjkavfh
-> kenshi_info log: https://ufile.io/sy0ka062
-> havoc.log: https://ufile.io/k9axipzn

Thanks for any ideas how to overcome this. Without the possibility to trade, to hire someone or to act when approached by a gate guard, the game is unplayable.

Looks like any edit of my post is regarded as Spam by this forum's algorithm. So here another bit:

I'm just testing it some more with this starting group of six settlers. Trading within the members of my group works without a problem. Looting or picking up of NPCs as well, just as fighting them. I can also "hear" discussions between NPCs or within my group. Looks like this can be pinpointed to a problem with the dialogue system.

On the Steam boards I got the hint to manually remove the Kenshi folder and not delete it with the Steam delete function. I tried that, and it worked! Problem fixed.
