If you use Yanfly self switch/var plugin and you have a spawn that you use in multiple maps. When you continually map transfer spawns will stop detecting the self switches consistently.
To remedy this go to line 118 of Galvs event spawner plugin and add your Yanfly self switches "SELF SWITCH 1". SELF SWITCH needs to be caps and 1 being the switch number the self switch is on, not what you named it.
ex:
Code:
Line 118: Galv.SPAWN.sSwitches = ["A","B","C","D","SELF SWITCH 1","SELF SWITCH 2","SELF SWITCH 3"];
