!! Update !!
There seems to be a bit of a problem with GregTech removal. I forgot that GregTech adds world-generation, such as Pyrite Ore and Iridium Ore. I'm afraid that if we remove GregTech from the current map, the world may get corrupted because certain block ID's might not be in the world anymore when they were originally there. This is also why everyone needs to get rid of all GregTech items.
I'm going to go as planned, with removing GregTech items from everyone's inventories and then removing the mod itself. Hopefully this will not corrupt the world. If if does, then I will restore from backups and we are going to have to live with GregTech, unless you want to reset the map again. I'm fine with it, but resetting the map for the 3rd time; you guys might not like that. If you guys successfully do get rid of all GregTech items in your inventories, and we do reset again, I do not see why I can't just transfer all the player.dat files (your inventories) and just resetting your location to the spawn of the world.
This is a big change, not as big as the FTB Modpack change, but still, getting rid of a mod that adds world-gen is a bit difficult. I need your opinions on this change. If everyone is ok with a map reset and I just transfering inventories over, then I could probably get that done today or tomorrow (you need to get rid of GregTech items! Do not forgot this!). I could also just go as planned with just removing the mod itself and hoping that the server world does not get corrupted. I need your thoughts on this.
Thank you all for reading this, have a Happy New Year!
