Yeah; I still know of both of these; and though I had added in things to attempt to fix them; they failed.
I plan to release 4.0 as my next edit; which wont be for a while yet; but all of these bugs have been fixed. there are just 300 more that you gotta watch out for!
Seriously, to deal with the hundreds of possible region problems; I have about 400 regions in 4.0 (compared to the 200 or so in 3.1) so that if somehow something at some point managed to go wrong enough; these extra regions would still be a safeguard against the wrong units entering the wrong regions. Well, that and preloading... which takes a lot of regions; because i remove what isnt used for some game, and add other things in...
Anyways /end rant dont worry about these problems with any of the elementals or archons in 4.0... (anyone remember what happens when you kill an archon with mets in a lane no one is in????)
