When I change mods sometimes it will glitch and the fighters wont reset positions. They will stay in the wrong positions so basically the mod is useless. How do I fix this?

Your talking about Multiplayer, right?
/se engageplayerpos 0

actually no Im not, just free play, like when I change mods sometimes the player positions seem to get stuck so no matter what mod I change to they will always be in the same position so the mod wont work correctly, unless by coincedence the mod im using requrires them to be in that position. ill try your code tho

even when i go to the tutorials the fighters are side by side.

Do what steve told you.

i had this problem once. what steve said should fix it up.
/set engageplayerpos 0

Hmm I'm having the exact same problem... and the command didn't do anything unfortunately =( I'm also having an additional problem... the duration of the mods also doesn't change, it's stuck on 500 frames. It also seems that I can't change any of the options/gravity/etc on the game rules.

Does anyone have any other suggestions? Perhaps something that I could reset?

waoo..thanks for sharing here
