A crash recently ate my enhanced charm of dislocation and creating a new one did not restore my (extensive) list of teleport locations (including my underground factory!)
Please... please tell me there is a file somewhere on my computer that has a list of those locations... something I can edit with a Notepad or something like that...
Sorry but as GreatOrator said the data is stored on the item. The only way to get it back would be to get it from a recent backup of your world. But i know most people dont make regular backups so that may or may not be possible in your case.
Do you mean the energy core? If so that is a bug that will be fixed in the next release which should be coming out very soon. Otherwise i will need the crash report.
