Oops, my apologies, I forgot I had that in there. Here is the reposted capx:
Though, I had this issue before I put the clay.io plugin in as well (which was after the upgrade to 103).
As for guidance as to when the problem occurs... Well, that is very difficult to say. I have had it happen almost immediately (I would be moving along and I would start taking damage, so I shoot the empty space and viola, it was actually an invisible monster), and other times it doesn't happen until later into the game. I wish I could be more specific, but it just pops up randomly.
All of my occurrances have been in Google Chrome as I do not have I.E. or Firefox to test. Hopefully someone else can add some additional information. I do believe WebGL is enabled, and there are no console errors that I have seen.supergodjesus2012-09-18 19:00:12
