Thank you for making a bug report.
As AMM has stated, replays can really help the team when finding out what is an issue and what isn’t.
I have gone ahead and confirmed that Nopenguin is not working at this current time with the following penguin names:
Penguin Cleric, Nightmare Penguin, Penguin Soldier, Fluffal Penguin, Glacial Besast Polar Penguin, Penguin Ninja, Penguin Squire.
The remainder penguin effect names have not been tested at this point in time, but I feel has proven the point.
I have brought this up to the team for further testing to find out what has changed. Please stay tuned.
Once again, thank you for making a bug report and helping to make Omega be the best it can be.
