Hello, i wanted to join a server session and there is missing a 0.18.4 version. Can you fix or add version?

0.18.4 was deleted because it contains a critical error, and nobody should be using it.
It's VERY rare that I delete versions, and if I do it's for good reason.

0.18.5 is version 0.18.4 with the critical error fixed, that's the only difference. You should poke the server to update the mod. (If that's possible)

I couldn't re-upload it anyway, I deleted all my copies of it, and I don't use an SVN like Github.
