Please, tell me everything you know about this. What if I already have all of one object on it? Past Budget...
It's not too complicated. The easiest way to unbudget glitch a map is to have no items on it. You can have items on it, but it may take longer. What you do is for each object in forge you must spawn them in and then delete. Take a double box for example, you spawn your first one in, just delete it then, and it should unbudget glitch that object. If you already have that object placed on the map, and you wish to not delete it, select it, and set the object's maximum to the same number of double boxes you have on the map. In order for the budget glitch to work, all objects have had their runtime maximum set to +1. If you still need more help, just send me a message.
