After checking all ships that's what I have to say:
-Going up a slope is extremely slower than normal movement.
-Going down a slope is slightly slower than normal movement but faster than going up a slope.
-On 3 of the ships tested I have found a similar behavior of sudden glitching through the floors for a split second, it all happens on the lowest deck of the ships and usually at the back of it. It happens on Junker bottom deck near main engine, Galleon bottom deck next to light engines, and spire bottom deck next to light engines. I am guessing it can happen on any ship due to how common it was in the ships tested, maybe I was not walking around as much. It's really hard to reproduce but definitively exists(my guess is that it has to do with low decks and random ship movement of bobbing up and down).
-All "magnetized" fences and surfaces seem to be fine, with the exception of perhaps the spire's railings on the spiral. I am not sure if it's the spiral movements and thus the pushing outwards that gives that notion or if it is actually still weird - maybe if more people check so we have a more strong opinion about it.
-A specific problem on the squid that you are able to glitch quite easily to the left of the stairs leading down to the armor, and getting stuck there still exists.
I thinks that is about all I found out.
Thanks
