Whenever I try to setup a mob grinder, I put Tinkers' Construct weapons in the autonomous activator, I drop down occasionally to check if things are working out, but soon after I get a message in my chat saying "Something weird happens around you." I don't know what it means, but I either get sent up into the sky to land on an 3 x 3 ice platform or get surrounded in a dirt shack. I get this a lot lately and don't know how to stop it or which mod it comes from. Can anyone help me? I would also like to know if it is from the Tinkers' Construct mod.
