Hi there, I have a few things to report.
Firstly, my horse cart frequently bugs out, the physics go crazy and the cart flies around in the air, consequently distributing my crates all around the map. Seems to be when an NPC walks into it or when I attempt to make, what I can only assume is a too tight corner. (also, one time the spiralling cart hit me and sent me up into the air and when I landed I was glitched into the floor, had to reload).
Next, sometimes I can't actually grab the crates from the cart. This one is a bit random and after a few minutes or a reload it seems to work again, just thought I'd point it out. (It's like the crates are blocking each other in).
This one could be my incompetence rather than a bug, I'm not sure. I went to the parts store and loaded the crate with a load of grips, paid and walked back to my shop with the crate. When trying to take the stuff out of the crate I was seemingly unable to. All I could do was grab the crate. The items inside highlighted in green when I hovered over them but I couldn't actually grab them. I took it outside, stood on the box and tried to grab them again only to be flung into the air, sent flying in a random direction and lost the crate altogether.
In the mine, I took a crate in and it oddly glitched to a spot. Not sure what happened, I placed it down and it was as if it was tethered to the spot. I could still grab it and move it a little but when I let go it would fly back to the spot. If it helps, it was just to the right of the first ore vein on your left as you walk in.
Occasionally the lantern on the cart will disconnect itself from the cart and hover in place.
Horse sometimes maligns itself from the cart. I believe it is the horse maligning from the cart and not the other way around.
I'll post anything else I can think of. The game is really fun but as a result of quite a few things bugging for me I'm going to come back to it at a later date, good luck with the development!
