So on the server we have been having trouble with setting up MultiInv. Currently there is no access to the End/Nether since inventories don't seem to want to carry over. We have a total of 3 different worlds. Main/Creative/Tutorial. However we can't seem to setup the nether/end for the main world. We have tried to change it though it has seemed to wipe every players inventory. I am also not sure.. what exactly to change none of us really do know..
This is what files came on default with MultiInv for us. Which doesn't look right from what I have seen by others.
From this I feel like we are missing some other things.. We have tried to change it like I said before though it had wiped all players inventories when we had changed it.
I do hope someone might know something of this plugin and be able to offer some advice or a good layed out tutorial one what is wrong. We may try re-installing the plugin as well in case the files are wrong.
