I had something weird happen to me a couple days ago. I was down to the 3 level in a dungeon I am working on. I added a set of steps down to level 4 and then went down and added a set of steps up. I checked to make sure I had no errors and then saved the file and exited to test. Well when I tried to load it into RTC I got a ton of errors. I loaded the editor back up to find that alot of level 3 was gone as well as the stuff I added to level 4. The floortiles were still there just the stuff added to them was gone. I usually make a back up when I am adding things to test out in case I screw up so all I had to do was load the saved backup and redo the last part of 3 and stairs down and up. Not sure what I did to screw it up when i saved but I thought i would post it here so that others remember to save backups often.
The other thing I was wondering is the "ref" appendage thing i keep seeing. Maybe I missed something posted somewhere and I wanted to ask about it. Is every getting the following:
; Level 0
ref000002-1 FLOORITEM_TELEPORTER 2 0 0 OPBY=(PARTY) DESTINATION=(1,11,1)
ref000007-1 FLOORITEM_TRIGGER 7 0 0 OPBY=(PARTY) ACTION=(TOGGLE) TARGET=(ref000107-1) OPTIONS=(SOUND:SOUND_OTHER_CLANK)
I did'nt see it in the maps that come with 0.28 until I saved something from the editor. Sorry if I missed a post explaining this..
