An exception occured in the reactor: WTelegram.WTException: Cannot find type for ctor #whatever after upgrading to v4.x

[13xforever]

In #191 it is stated:

In which case, some errors like this may show up ONLY in the logs and WTelegramClient should be able to ignore the errors and continue execution normally

But I've tried to upgrade twice from 3.7.2 (first to 4.0, and today to 4.1.1), and all I get are these exceptions and no events being triggered in OnUpdates at all, so basically nothing works, and rolling back eats the events that were received by 4.x client.

full stack trace I get in the logs on new message:
