Subs and crabs broken and also tame issues

[hillbllywsperer 13]

We made 4 submarines and went to the trench in D12. all 4 got stuck in the middle of the water not touching anything as soon as we entered the trench and there were other peoples subs stuck down there too. Then we tames 3 crabs brought them to our boat and loaded them, went from D12 to C12 and they all disappeared. Also when tames are put on neutral some time they go nuts and start attacking like they are on aggressive. We have had bears jump off our boat and attack SODs in open water. Please work on these things.
