Hi there!
On the error log, I can see at least two more plugins other than ARPG_Core that are conflicting. I took a look at my ELIMZ_Book plugin, and the error is being "triggered" on the Alias of the function:
Alias.Game_Event_initialize = Game_Event.prototype.initialize Game_Event.prototype.initialize = function(mapId, eventId) { this._mapId = mapId this._eventId = eventId Error is on this line => Alias.Game_Event_initialize.call(this, mapId, eventId) }
As so, I'm not sure what is going on. Maybe it is just a matter of you change the plugin order. Try messing with this, putting my Eli Book somewhere else on the plugin manager.
It seems to me that something is trying to access a .x property of something, probably an event. Which event is that? Is a regular event or a spawned event? Only with this information I cannot say for sure what is the problem.
Let me know if changing the plugin order will work. Otherwise we see what will do after that.
That said, after adding another plugin of yours called EliMZ_CharManager. It breaks everything again after the game load player sprite, no matter the plugin order, I tried everything. I haven't done anything yet with the said plugin. Any idea how to resolve this?
