Dedicated Server Failing to Start - Mythcraft Related

[Katherine1]

So we played for a while and everything seemed to run fine. I decided to shut down the server to back it up and then start it back up. When I tried to start the serve back up, I got the following Error Report:

---- Minecraft Crash Report ----
// I let you down. Sorry

The server will not start back up now. Is there any way to save this server?

I get the Server tick loop all the time on SSP. I suspect it must be an inherent flaw with the way the modpack is built, as it seems to happen no matter the mods used or what server you're on.

Found it. It is a known Mystcraft problem:

Cannot Load World: Log States There Is Already a Provider for DIM 0

This is a known bug related to spawned Descriptive Books. Deleting SAVE/data/agedata0.dat will fix this error.

Thank you very much for sharing the sollution.

 

[Katherine1]

No problem, and just to note, do not delete any higher numbered agedata files. Those are the contents of all your descriptive books. Everything will work fine if you remove just the one listed.

Where do you find the agedata files?

 

[Katherine1]

Right where that quote says it is. SAVE is the name of the world. the file may be named agedata_0.dat either way, only delete 0. All files above that are all the descriptive books you have made.
