1.) My Parallel Process Event won't run whenever I'm talking to somebody!
Why? The reason why this happen is because of how RMVXAce handles event processing. This is due to Fiber.yield. It's going to be a long explanation and the only way to "Fix" this is to rewrite the game interpreter or the message system. But fret not, there's a way to fix this!
Why should I be concerned? If you like making animated events through parallel processes, they would stop whenever a message box is visible!
How to fix? Just put the commands of the parallel process event inside a loop or use labels. It will run normally~
2.) Shift Mapping destroys auto-tile passability!
Why? This is intentional and only works with ceilings but not on walls. Unconfirmed, but it might only be A4 wall tops. Someone check this out?
Why should I be concerned? You can walk through autotiles for ceilings.
