Bug/Issue [Fixed] Issues during Big Ape fight/Dungeon

I'm doing a multiplayer run with a friend right now and we've gotten to the big ape fight, but during the dungeon run we've had the same two problems 1.) the farther into the dungeon we go the more lag my friend and I get, and when we get into the boss arena with big ape my friend's game becomes unplayable (we both have decent computers that have no problem running the game and our internet is fine until that point) 2.) the game almost always crashes once we get to the 2 pod mark. This has happened to us every time we try to do the boss fight, so we can't progress any further for now. The weird thing is that when my friend uses an endgame character on solo mode he doesn't crash or get any ubsurd lag. (multiplayer only bug?)

We're both on Win10 Anniversary 64bit, I'm on borderless windowed and my friend is on fullscreen and neither of us are using mods, and I've already uninstalled and reinstalled the game and still have the issue.

When I look at my folders I can't find any error logs but I do get this error message

Do you have any mods installed?
And could you give me a link to your starbound.log I just may be able to help.
Also if you could give me log as fresh as possible that would be great.
