Same problem, on dev+72

Guys, if you use dev+68 it is working normally again. In dev+70 was a change about Emoji-Jetpack or whatever, and THAT was the issue, as it seems.

using dev+68 now and no error if I write in the discord-channel etc.^^
Not the best solution to go back, but at least one for now ^-^

Guys, if you use dev+68 it is working normally again. In dev+70 was a change about Emoji-Jetpack or whatever, and THAT was the issue, as it seems.

using dev+68 now and no error if I write in the discord-channel etc.^^ Not the best solution to go back, but at least one for now ^-^

Unfortunately this would still have a duplication bug that I wouldn’t want to be used 😬 it’s fixed in the most recent. I’ll just wait for the discord part to be fixed over an exploit.

this is not the case, there is not a single change from the previous build there, just has to do with our build system.

misread the issue, I see the issue now

[JRoy]

Should hopefully be fixed in the latest build.
