people cannot open chests when joining my server

when people join my server on my TF300 tablet (android) they cannot open chests when they click on a chest to open it the game will crash and you will have to get all the way back in the app.

*What I expected to happen was...the new update 0.6.1 was going to fix this problem because it was also happening in 0.6.0 i thought they would be able to open the chests just like normal.

*What actually happened was...: they joined my server and they clicked on a chest and their app crashed

Steps to Reproduce:
1. make a server on android
2. ...have someone join the server
3. ... click on any chest and their app will crash and get disconnected
