[help]making house permit and upgrade cert undroppable

Hi what I made a little house code nothing much. Might actually make the whole proccess like the vouchers and stuff but what I need now is how to make a house permit and upgrade certificate undroppable and untradable.

Thanks,

Make a case and then add delete = false.

Actually, in dropitem.cs

Where it deletes it from your inventory, and adds it to the IG array. Just add
where 000000 is the ItemID of of what you don't want to drop.
