Creatures Caves

I am running DS and C3 on an intel Atom x7 prosessor, so it doesn't handle big loads very well, and this becomes a problem when my games starts building up a heavy amount of plants and critters.

When C3 and DS were new, there used to be an agent the reset the ecology, to make the world less heavy on the CPUs.
The agent doesn't seem to exist anymore, so I will have to use ject commands to remove and reinstall every plant and animal in all terrariums on a regular basis.

I have no experience in scripting and coding, but was wondering if someone could slap together an agent that did this in the various terrariums. Not sure if this would be hard or not, as I know nothing about how this stuff works, but I would guess the agents would be simple to build, and would be compiled of the ject .cos files in packs for each terrarium.

Thanks for any help or comment! <3
