HELP with bug on map

Hi im really reaching out in hopes you can help me recover some farm i lost. I had made ore teas and i was out farming in a ravine for 30 minutes, i had gotten down to the middle area and i just fell through the map and got kicked for a invalid map violation or something along those lines. I join back and tried to go retrieve my bag but i just keep falling through the map. Is there any way u guys could help me get back my farm or even some of it. Please help
