Tokens on Uniswap can usually be traded on multiple pools. Logium allows betting on a single pool for every token. We usually choose the pool with the highest liquidity, because the higher the liquidity, the more costly price manipulation becomes. However, sometimes liquidity shifts between pools and a pool that is listed on Logium is no longer the most liquid. In such situations we change the listed pool to the more liquid one. If you issued any awaiting bets on a pool that then became delisted, they will stop being displayed to other users in the UI. If someone took one of your bets and then we delisted a pool, it will be exercised as it normally would.
