Ram controller issue

[Vennicus]

So I've got the latest dev branch and co-op scripts but I keep getting this error:
NLua.Exceptions.LuaScriptException: .\bizhawk-co-op\sync.lua:104: attempt to index upvalue 'ram_controller' (a nil value)
as host and:
Error during sync: .\bizhawk-co-op\sync.lua:200: attempt to index upvalue 'ram_controller' (a nil value)
when connecting to someone else.

Everyone running new scripts
