If you're working on your set in the NeoLemmix v12 format, please remember:
When you create or change a graphic set, to get it included in the next update of NeoLemmix's styles / updated in the Style Manager's download functionality, please create a .zip file of your graphic set and send the .zip to namida by private forum message (https://www.lemmingsforums.net/index.php?action=pm;sa=send;u=1). Please make sure it includes sound effects as well as the style itself.
Please be aware - it is your responsibility to make sure NL's developers are aware of the updates to your styles. Do not rely on them seeing that you've posted on the forums - contact them via private message on the forums (NOT via Discord or any other means) to let them know.
This will help you in the future. ;)
