I just downloaded QABS (as well as the HP bar addon, the skillbar addon, QPopup, QSight, QPathfind, and QCamera). I'd already had QPlus, QMovement, QM+CollisionMap, and QAudio installed, and the game still works fine when it's just those plugins turned on. However, when I have QABS turned on and start a playtest, then hit "new game", the game lags for a couple seconds (as in, I've hit f2 to watch the framerate, and it hangs at the number it was at when I clicked "new game". Though it's possible that's just my laptop being slow.), and this error turns up. Before I hit "new game", the game acts like everything is normal.
It also doesn't report the same thing each time, for the "at <file>" bits. This is another one that I got, with the same exact plugin setup and the exact same steps.
Also odd is something else that happens with this error. I'll hit f8 to see the console, close the console, hit f8 again (and the "at <file>" bits will be different), and this will be added to the console (I've seen it appear both above the "at <file>" parts and below it).
But when I check the QABS demo (and the NewData folder), no such files exist. There's files called "pixi.js", "pixi-tilemap.js", and "pixi-picture.js". But nothing with the .map extension.
For reference, I tried to figure out which plugin(s) were causing the error by turning off all of your plugins and then turning them on one by one to see when the game would throw the error. Turning on QABS made the error start appearing. Turning on QPathfind doesn't cause the error, nor does turning on QCamera, QSight, or QPopup.
