Yeah, there's a few issues.
I have the unprotected version of Myths and I believe I fixed the bugs in the triggers.
But fair warning, I'm not a triggerer. I'm a hard programmer. I do everything in JASS/LUA. If you are a GUI user you may not have much luck with the triggers I've made and converted already.
Also, the Myths original map does not actually work. If you try to save it, it will corrupt and break. Hence the need for new terrain. I simply exported a few key functions, converted them, fixed them up, then imported new systems into it (Timers, Spell Utils, Stat Utils, Save/Load System) while creating/exporting my own vJASS code.
When I get the chance I'll try to send you both my map progress so far and the original Myths.
To be honest I might still be willing to work on it, but only so long as I don't have to reterrain it. Also can't work on it til the terrain is complete.
