Log (if crash occures)
Link to crash log

Well, first of. Do you play on a server? If so, is the mod installed on the server?
Also, the versions are not the right ones. We need the mod versions not the minecraft version 4 times.

From what I know the issue persists on the server side only

Is there a crash happening? If so could you include a log?

I have the same issue. Not playing on a server. the backpack mod worked beautifully in the previous version, but in 1.9.4.63 it fails. when the backpack is in the hotbar and the slot is selected, right clicking the mouse does not open the backpack. instead it tries to place the backpack.

Do you have optifine installed?

As there is no response from any of the reporters, I'll close this issue. If the issue still persists please open a new issue.
