Okay, I have a new, honest question. I could lie and pretend I somehow reverse-engineered the problem but whatever:
Would people be angry with me if I lifted some bugfixes from other mods? I think it's ridiculous to have bugfixes thrown around multiple, non-weidu mods. If it's not compiled into a single release, I basically force the players to hunt down tiny files all over the internet. Also, I don't believe that bugfixes are too much of an intellectual property.
The general rule of thumb is, yes, no, yes no.
If the mod doesn't have a readme, then yes, if it does have one and it says not to copy the code then of course no, but it's usually not there... :devil:
And of course if you make a readme, make sure that you record who did what, aka thank people and their contributions, and of course you probably should try to get people to respond to your hails.
 
And yes, there's still every possibility of people not wanting anything to do with your work, so be tactful.
