This has only been a recent issue in Starbound. Whenever I try and play multiplayer my actions won't load for at least 30 seconds. I can move around just fine, but I can't open doors, chests, place blocks, or damage enemies without waiting forever for it to register. I'm not sure what is goin on! Single player works great. The server I set up for me and my girlfriend works great as long as I'm the only one on it. I don't know if the problem is my computer, hers, or what! I plan on doing some more tests tomorrow to see of she can join me via steam or what happens if I join the server first. We both have a ton of mods if that matters. Has anyone else had a similar problem and fixed it?
This has been a problem for many players (inc. me) but I think it'll be fixed (hopefully) on the latest patch > w> E a.k.a. no fix yet...
