They had a problem with the decimals display on some wallets. For a short period of time some people could change their tokens into D & U, but not it is disabled till they fix the problem with decimals. I hope I got it right, more info on telegram. You dont need to panic, the team is working on it.
This is correct. The decimals display incorrectly on 2 block explorers and etherdelta. The process is on hold now while the team fixes it. More information will be posted later, with an email sent out as well. Thank you for your patience.
