WM contraptions on saves?

Only for me wiremod contraptions screw up in Singleplayer saves? And I can’t seem to remove it after… getting this errormessage;
“includes/modules/constraint.lua:167: Tried to use invalid object (type IPhysicsObject) (Object was NULL or not of the right type)” in console.

Is it Garry’s Mod saves that are screwed or Wiremod?

I’ve got the latest Wiremod using SVN.

Garry’s Mod saves havent worked correctly in a long time. I advice you to use advanced duplicator.

Yes.Gmod saves also mess up for Stargate and Life support.What I suggest with Wire and Life support is simply to smart constrain them and then Adv. Dupe them so that everything is saved.

Fair enough, thanks.
