I will say this glitch is extremely unfortunate and I for one believe that this is not a good look, KL is a popular character and a lot of people play him. Whatever decision should be made, I don't really think ANYONE wants to make. I thought this is what the hotfix system was for, but it appears that NRS has a lot on their plate and cannot do it before Combo Breaker starts and must be patched out. (They just finally fixed the Ermac meter drain glitch.)
MKX could of used a delay, tbh. (Warner Bros likely would not let it happen though as developer deadlines are a real thing now.) The Spectral Ermac glitch made no sense to me how it appeared and was not found quicker in development in the first place, and now we have this. Of course things are found in games and things do take time to patch out, but this is such a glaring bug that IMO ruins the character and I would find it really hard to tell someone "You can't teleport or do Hat Toss." or "because we just found these bugs with his wakeups/moves, he's now soft banned."
I'm honestly glad this isn't a decision I get to make.
