Hi! So I decided to make a server with some mods on it for my friend and I but when we tried to use the crystal ball to set our gender, we'd click on the gender we wanted and it would crash. We have tried it with just MCA and with all the mods and it's the same. Googled every possible thing and nothing helped. We are running forge-1.7.10-10.13.4.1558-1.7.10-universal and MCA-1.7.10-5.2.2-universal.
