TY Greg… But there is something behind scene…
First time ill try to enter to my World, FML say "FML detected that the backup level.dat is being used. This may happen due to a bug or corruption, continuing can damage yuor world beyond repair or lose data / progress. Its recommended to create a world backup before continuing " So i create copy of my world and try run this copy. Then OutOfBounds error arrive - manytimes.
May i use old Backup.zip to recover my world? because last time i log-out ill be in middle of my base… I dont want to lose chunk of my Long-time work (being Tantalum processing). Few day rollback is better than few months of work(fun).
