I know that objects in vehicle beds, etc. has been mentioned. But I wanted to show a clip of the behavior that I witnessed just now. I've been having no issues putting the blue container in my truck, along with a gas tank. I go to water tank, fill up the blue container, come back to base, move container near my storage farm and unload water to prepare for winter. That' NOT been a problem. Maybe the hippity hoppity truck, but no driving issues, etc. Until today...experimental 11444...
I have a container and generator in my pickup bed. I had just grabbed a generator from a cabin, came back to base, and did some things. Saved game last night. Logged on just now, and prepared to head out for the day. I opened my gates...and tried to leave. The CONTAINER and GENERATOR were FIXED in place, like an anchor. The vehicle tried to drive forward and would "hit" the container and generator, causing damage to vehicle and my person. I was able to move the object out of my truck, and move the truck with no issue. I then put the generator back in the truck bed. I was able to pull ahead without issue.
If you watch the video, you'll see that when I put the generator in the bed and jump in the truck, the screen goes black for a couple seconds as well. That's a new issues as well. But I've never seen this boat anchor behavior, and wanted to ensure Devs could clearly see it. Hope it helps!
