When a market resolves N/A, Manifold basically treats it as if the market never existed: Profits and losses are removed from the accounts of people who made them, all the mana spent on shares and subsidies is returned, and the creator gets back the 50 mana required to make the market but loses all the unique trader bonuses. However, the unique trader bonuses are not really part of the market itself - they are more of a meta aspect - so it would be possible to have markets resolve N/A while still allowing creators to keep the bonuses.

On the one hand, removing the bonuses is useful because it discourages N/A resolutions in cases where they are unnecessary and encourages creators to make the resolution criteria clear, since they wouldn't want to have to resolve a market N/A due to unclear criteria. On the other hand, it also discourages creators from resolving to N/A when that really should be the resolution, if they got a bunch of unique traders. For example, creators may decide a definite resolution despite a very ambiguous situation that is not covered at all by the resolution criteria, or they may resolve to PROB instead of N/A. It also discourages creators from making conditional markets.

At any point in 2023, will Manifold change the way UTBs are returned after an N/A resolution? It still counts even if they reverse the new rule, or if the creator only gets to keep some of the unique trader bonuses (e.g., N/A causes the creator to lose half of the mana they got in UTBs).
