One more post to share tonight:
IF YOU HAVE USDE ON POLONIEX, DO NOT (NOT NOT NOT) ATTEMPT TO WITHDRAWAL IT RIGHT NOW.
They apparently have not updated their wallet. If you confirm a withdrawal with them it will say pending, then completed - but it will be on the old invalid block chain for USDe - and I would guess lost. Tested it with a couple thousand.
I sent them a support ticket on it (many of you may have as well) to ask for the wallet to be updated and us notified to test and finally use again - to get our precious USDe out of there and into our local wallets.

I think someone should check all the other exchanges as well if they are on the right wallet.
Last night I did shift 200k USDe from Crypto Rush to Poloniex. The full amount is still at Poloniex, but in which wallet? Maybe it is not a problem, dunno.
