So I loaded the world without climate control and it loaded fine, but after putting climate control back in it goes straight back to crashing :/
Interesting, well at least it's confirmation of the source of the problem. Unfortunately I have no idea what the "Saver" function does for this mod. So it would seem to be time for the "Fix random issues somehow" checklist (preferably in the given order, since it'll mean less work if one of the first couple work);
-Check that you have at least four gigs of ram dedicated to FTB through the options tab of the launcher
-Backup your saves
-Check that you have the latest stable version of Climate Control. It may not actually come with the pack, but if it works....
-Reinstall the pack
-Reinstall the launcher
-If all that does nothing, reinstall Java (your current version should be fine as far as I can tell)
So this happens when i log on to my server.
Anyone know why this happens? Can i prevent it?
That is a lot of chat spam. XD
Not sure sadly. Is it happening every time you log on, and since it's a server are other accounts having the same issue?
