Question about adding only a few things

Hi,
You can add additional items to vanilla loot by setting 'ClearContainerFirst' to false in the config entry for locked crates.

The problem is CustomLoot, when enabled for some crate, can't give out nothing.

So you'd have to have it give out supply signals every time, or balance them against some other less valuable item.

I'd suggest just picking a low value item like wood so, for example, set the config profile to give out maxItems 1, then have probabilities

Resources > 9    wood > 1
and
Tool > 1        supply.signal > 1

That way the profile would always give out 1 item, and there's a 1 in 10 chance that i'll be a supply signals.
