There are no problems with the PascalCoin Wallet. I've personally stress-tested and confirmed it is stable. Cryptopia are delisting for other reasons, more likely upset they aren't getting volume but many support requests since Polo users are withdrawing directly to Cryptopia accounts and they are unable to handle this (rather simple) workflow. I've attempted to reach out to them and offered free technical support from my software company, but they have not been responsive at all.
