When using the telescope, the gui instantly closes. The handheld telescope seems to work. I have tested both on a sponge server and on a non-sponge server running the exact same modpack, and the issue has happened on two separate modpacks.

Please search issues next time. There's no reason for there to be half a dozen duplicate entries for a fairly recent ticket, especially when the last duplicate was closed half an hour ago.

The last duplicate was with sponge and you closed it blaming it on sponge, which is why I opened this...

It's part of the same issue, had you read the ticket. Also the last closure was not blamed on Sponge it was pointed to that ticket. I simply mentioned that sponge is not supported.
