I have managed to finish my first map - a two story building with a cellar and roofs. It took me couple of hours and wasn't easy with all the glitches (all working area going gray from time to time was the biggest hurdle) but I was happy how it turned out. Everything has been finalized and prepared for the export to be printed (white background on all levels apart from ground level which was supposed to be my foundation - to be printed out in its entirety).
I came back to the map today (2 days after I finished it, I think), and now I can't access other level besides the roof which is the first thing that loads. The browser pops up a message that the page is not responding and waiting doesn't help. I've tried switching from Chrome to Firefox but the result is the same. Same goes for the export tool which gets stuck when I try to switch a level. Cloning the map doesn't help either.
I'm not sure, but at the end of creation process I've used brush tool a lot, to make the surrounding grounds more interesting. The thing is - I was still able to reopen the map without problems two days ago.
Here is the link to the clone of the map:
If anyone can help me to solve this problem, I will be very grateful. I've poured several hours into it and will be very disappointed if I loose it all. If it is caused by the high amount of brush strokes, would it be possible for the dev team to delete them all from the map?
Edit: While writing this I was fiddling with the original map save a bit, trying to see if anything will help. I've managed to turn off the 'Show Stage' option on the Roofs level. I've also activated 'Hide all lights', turned off 'Allow Ghosting for Levels Above' and made a save. I can sort of switch to another level now but nothing loads (gray working area) and I still get page not responding popups. I even tried deleting two biggest levels (Ground Floor and First Floor), but the browser still times out.
