I think this may be due to a mod conflict, perhaps something that recently updated.
Several days ago, the boat was working just fine, but today I noticed that I was unable to move once I was in the boat. I could get in and out, but that's it. I tried picking up the boat and re-placing it, but it's showing as red on every surface.
Here are the other mods that show up when I select the boat:
- Endgame Combat
- Natural Evolution Enemies
- AAI Programmable Vehicles
- Hovercraft
- Attach Notes
I'll do some more testing on my end to see if I can narrow it down.
Edit: Further testing reveals that it IS a conflict. Not sure which mod yet though. It's definitely not any of the ones I listed :-/
Edit 2: Looks like the problem is probably Hovercraft when used in conjunction with Taterjr Space Station. There's a thread in the latter's mod page saying that it can be made to play nice with Hovercraft by setting the Floor Collision value to 13. Testing that now...
Edit 3: It's definitely those two mods. 13 is the default value though. Changed it to Floor Collision = 14 and that seems to have fixed it for now.
