Initial Experimental build #7978 (or #7979) to current Experimental build #7995 (continuously updated the experimental build as I played on the world)
Windows x64 Tiles
I installed two empty 60L vehicle tanks to my immobile, home workshop and tried to fill them up with water (frozen) collected from the rain. I utilized the vehicle menu UI to fill the tanks. Then I got this error from the game.
Later, I tried filling it with water (hot), a plastic canteen amount of frozen, cold, and hot water, and still cannot fill the tank up. After exiting and entering the game, I believe the frozen 60L tank of water disappeared out of the game. The game started out with the nut update (#7978?), and I kept updating to update #7995 as I played.
I have not tried any other workarounds or other liquids than the ones I have mentioned.
I believe this is a new bug introduced in the recent builds because I was able to refill vehicle tanks with water in pre-#7878 build.
