I like that you are bringing some of the corrections from otservbr such as this one opentibiabr/otservbr-global#442

While cherry picking, a good pratice is to reference the original author to give credits. Especially in your case, where you're constantly snobbing the project but it's following it to the point of being able to copy things in a time frame of a few hours.

as you can see in #3966, let me show you a bigger picture:

so... no, the world doesn't revolve around your guys code, while I was taking a look at #3966 I noticed my pitfall was not working, but kudos for trying to look relevant.

PS: I never had any issue giving proper credit when applicable as you can see here: #2795
