No, there is no reason. It just threw an error when I enabled that mod. It's probably incompatible with one mod, and I didn't have enough time to figure which 1 out 500 mods is incompatible. But, it might work now. I want it to work. :)

I have Biotech DLC and would be interested in the vanilla races expanded series of mods. I checked the incompatibility list on the multiplayer mod and it says they require the multiplayer compat mod. Is there any reason installing the compat mod would break your original multiplayer list?

That's ok! Your english is good. I removed "Worthless Junk". If you prefer "Worthless Junk" over "Dismantle Ancient Junk", please tell me, and I will add it back! Thank you for the report.

dismantle ancient junk is incompatible with worthless junk (im spanish sorry for the bad english :D)
