WGT usually won't delete a RG tourney even if there was some mistake ... they just let it run it's course and not create a new one with the same parameters ...
I've seen it happen with the 5 cent or 2 cent RG's ( I don't remember the exact entry fee, but it was low) , and the RG's that WD every player from the start ... there was even a glitch once where you could post several scores in one RG ...
There have been 50 dollar RG's before ... it was around Christmas time in 2011 here's the LINK...
Probably they will let this one run its course ... they had a Tour Legend RG go almost 6 months before filling but they let it roll right along ...
