@xclency, hello there, thank you so much for your discussion comment (
question) anyways, yes it is not allowed to re-sell already paid resources; based on the real author
TOS but if you did read my
DISCLAIMER you will know the real reason or purpose but if not here is it;

Aside is, it does not have ItemsAdder configs since the purpose on this packs was focusing only on the new release plugin which is the plugin
Nexo;

And for your question "
And are the custom model numbers set at a high value compared to the usually used ones like below 20000" some of the custom models that usually have default ones like lets say for example on one of my custom model sample;
The very lowest number was
2177 now by using my python program that I have created, if the below model was
2300 then it would be automatically replace into
2178 and so on, and then by using the
nexo plugin multiple configurations that requires changese on models will be automatically change, as also you can see on the screenshots I have provided on those
spoilers you can see that there is no items or packs in there that conflicted and there is no error also in the console, plus bunos that you can freely change it by yourself and easily due that I have manage it to put on each folder which means all is categories, you can freely removed all you want or you could just follow my format if you add something new and it will work as fine ;)
