Copy/paste into an existing mod works very well.

So the thing to remember now is : ***the host should ALWAYS START A MP GAME WITH A MOD ENABLED***. In the future all players of all mp games should have a blank mod, and the host should use it at game creation, then hotfixes for bugs like this one won't be a problem, as well as game evolution (say things like playing with the latest edition of a cbmod) or scenarized games (we can even imagine a blank mod being used to play the 3 ages... or more in a game, modding all the nations each x turns into the next age version).
