MC-20257 Crash when chatting on modded server Resolved

Comments 4

Neospector 2013-07-16T16:23:07Z

Duplicate of MC-20163
While that says it's resolved, it's only as such because the original report was concerning a modded Minecraft server. The issue still apparently persists with vanilla, so monitoring that ticket may be to your benefit.
Remember that "Resolved" does not mean "Issue is forever closed and will not be fixed or changed in any way"; if a ticket "Works as Intended", suggest it be changed on the Forums or Reddit. If a ticket is "Invalid" due to the client or server being modded, be sure to try and replicate the bug in vanilla, and if you can, post it on the closed ticket so that it has a chance of being reopened and fixed in the future. You're perfectly able to report bugs, even if the original ticket is closed, without creating duplicates and with that, spam.

Next time, attach the crash report rather than just pasting what it said in the crash report.
