I have a large custom modpack for 1.7.10 and our server has been working wonderfully up till this point when something very strange has happened... I spend a lot of time figuring things out for myself so coming here is very much an act of desperation and it would mean the world to me if I could get some help. We have spent countless hours on this world and I dont have a backup anywhere near where we are.....
So it appears that for some reason when anyone logs in now, they get in far enough that they see the sky and turn around but not see anything in the world itself and they are falling through air. Then they get a timed out message however it doesn't log that they got disconnected on the console for another couple minutes, and there is always a huge number of ticks skipped after the player tried to log in. This is especially strange given that the norm was it would take several minutes to be able to interact in game while it loaded, and during that time the console would show monsters spawning near you via JAS mod. Now it is the opposite, with the client getting in right away but the console never spawning creatures and not logging that you disconnected (timed out) until way after the fact. The server never crashes and seems to have started up just fine, and this issue has never occurred before.
I have tried:
* using Minecraft Region Fixer which showed no corrupted regions
* deleting the level.dat and other files, or replacing them with backup versions
* using McEdit to delete almost the entire world outside the main spawn area
* deleting all other dimension data
* deleting all player data
* trying the world on another hosting service
* deleting large amounts of mods to see if that fixes it
So far, none of the above has worked....
The mod pack I'm using has not changed at all and all of these mods were working together up until this point without issue.
Below I will post some images of what happens on the console and client-side, as well as logs from both. Let me know if there is any other information I can provide!!!
