[Trading error]

Ok I found the solution, Im pretty noob

The wrong part was that we both chose "request trade"

one must chose "request trade" and the other one "wait for request"

[Trading error]

I saw this error at other topics but no solution, When I try to trade with a friend I get the following error:

 

Script 'Trade' line 442: NoMethodError occured.

undefined method 'visible=' for nil:NilClass

 

Anyone got any solution to this? I play the latest version
