In the situation where a market is about to close at a number different from its current probability, is it ok for the creator to correct it right before closing? (Where "ok" means "the community isn't going to be upset at that person or more reluctant to bid in their future markets".)

Does it depend on whether the market is about a personal detail? For example, if the market gets "will Russia do X" wrong, is it more acceptable for the creator to correct that market than it would be for them to correct a market of "will I do 30 pushups this week"?

(This is all assuming no dishonesty or other manipulation on the creator's part; the market legitimately got it wrong or didn't have enough information.)

I'll resolve this market based on what seems to be the best answer according to the comments. Note that if 51 people say it's fine and 49 people say they'd object, that will result in the market resolving to NO, since having 49% of traders not want to bid in your future markets is still a significant cost to incur. If people agree on a mixed answer, such as the Russia example being fine and the pushup market example being not fine, I'll resolve to PROB 50%.
