Command block will not output a message past a certain character limit.

[Dravitch]

Issue: When I, for example, have a command in a command block like, "/say a bunch of stuff", the command block will only say messages before a certain threshold of character limit, as in about 260 characters. I've checked my mod configs but haven't noticed anything that would impose such a thing. It's such a random issue that I only noticed now as I've been on & off of Minecraft recently. If anyone has similar experiences or know of a solution before I troubleshoot by removing mods one by one I would appreciate it.

Also made sure that it's not a server config issue, command blocks are enabled, gamerules to show output of command blocks is enabled as well.

Have you made sure this doesn't happen in vanilla. If it does, it belongs on the vanilla bug tracker (if there isn't already a ticket for it).

[Dravitch]

This is not a problem with vanilla. Command blocks do have a character limit but it's far greater than the 260 that I'm having an issue with.

[Hipposgrumm]

But is this reproducible in vanilla? That's what I'm asking.

If so, it's not a Forge problem.

[Dravitch]

This is not reproducible in vanilla. It works as intended, I can have over 260 characters and do a /say command and it will output the message as intended in vanilla. If I do this in forge I can't get a message to display with the /say command when it is over 260+ characters long.
