This is entirely unlisted (ie noone outside your server can see it)?

Then yes, provided:
1) It is never shared outside that environment
2) You do not claim credit for the mods, only your changes
3) People are made aware of your changes, so they do not report any issues they may cause to me
4) The changes are "legitimate gameplay/balance tweaks", not things like making them only harvestable by people who donate money or filling them with obscene language on signs

Hey Reika,
Can we have permission to upload a mod with some of your content for private use with an unlisted posting (i.e. for a server). We would want permission to tweak the ships for our custom scenario and factions. Also if this only applies to certain mods of yours could you please let us know?
Thanks,
Strike

This mod has been updated, fixing all the cargo load issues as well as upgrading the ships themselves.

Yes, but it still works in the game.

Are you still planning on updating this?

ok thanks for the reply

I know; the system for mods to add random loot to cargo ships does not work, and such a thing may not even be possible. If I cannot get it working, I will just add nonrandom (ie always the same) loot.

Hello the ships don’t seem to 5o have any loot in them?
