So I have no idea what this means. I gather it has something to do with drawing shadows on events, and it's encountering a problem doing so. Why, though, escapes me, as I haven't modified any of the script classes named in the stack call in the error message. I will note this only occurs when attempting to warp to outdoor maps. I was not able to reproduce the error in a clean Essentials.
Why is it throwing this error? I remember there being something in an older version that drew shadows when there were light events, but I haven't made any of those... And since I can't find what the call is from, I can't isolate the problem. Bleh, I should be better at this considering I've been studying programming for 3 semesters now.
Okay, so, it's back. I don't know why. I still haven't touched any scripts. This time, the error occurs on only one map, and it seems to do so when the player is close enough on a connected map for the map in question to load. The only things I did leading up to the re-occurance of the error were to change the tileset and the layout of the map, neither of which I should suspect would be the root of this problem. Since I have no idea what the stack call is doing, I really am at a loss as to how to fix this.
Yep, that did the trick. Thanks a bunch, man. I'm not sure what part of the map exactly was causing that problem, but thorough replacement fixed it, so I guess it had to be at least one tile somewhere.
