otclient's packaging is incorrect so it's not going to be allowed into the binary repositories until it has been corrected.
The package.yml will need to be corrected to either clarify that using Tibia tarballs is permitted for distribution, or remove
the mechanism entirely.
I will leave this issue open for a few days only.
Note it is my belief at present that redistribution is *not* permitted, thus the package.yml in its current form would only be appropriate for a third party mechanism or a Snap, or similar.
Redistribution is definitely not permitted, especially since ot is a competing product using CIPSofts IP. There have been very clear statements by them a lot of times, and you get banned of the game/forums just for mentioning OT.
They have been/are hiring IP lawyers, and my bet goes for they are about to do something against servers and redistribution of their IP for a competing product.
Thank you @STiAT - good to have definitive answer! Well - I'm marking this resolved. People can help us by looking at the source lines in new package.yml's in the patch queue to spot anything that looks suspect.
Cheers :)
