Ill try to search if it was an incompatibility, but so far I have fixed it. It seems this mod actually benefits from being higher up(later) in load order, compared to other mods.

@Jobaria tiguidensis
Most likely another mod that's overwriting deep tanks? Try moving this mod to the top of your load order.

It seems like the deep tanks dont seem to be working for me? They are still their normal sizes.

I've looked into it for about an hour now, and it seems that changing the minimum size of tanks causes a hard incompitability with campaigns. I'm not convinced this is actually fixable?

For some silly reason, the campaign data IDs for tanks are tank ID+minimum size, so for the deep wall tank its 'wall_1side_deep_3_3`.
I'm not sure why they're even tagged with the minimum size as it functions perfectly well without adding that info, this also means that every single level is broken in a myriad of ways, as for example things you should start with won't ever be unlocked in said levels.

Overwriting the base campaign files isn't possible either, at best I could provide a fixed copy of the base campaign, but that comes with its own heap of problems + it'd require me to go through every campaign data file with a fine toothed comb, and I'm not sure if that's worth the massive time investment?

Thanks for the bug report though, even if it's provided me with a massive headache! :)

Really good mod, but be aware that for some reason it bugs the "research deep wall tank" objective in the campaign, no issue for sandbox tho

woops, I used that to mark the 'bottom' and 'top' pieces initially when figuring out coordinates, thanks for the report, fixed now :)

Awesome news! I did want to also report that the maximum size for the Large Tunnel Tank has some blank spots https://media.discordapp.net/attachments/334862477940490250/1176558404265836554/Megaquarium_2023-11-20_9_07_14_PM.png

Yes! It's mostly done already actually, there's just a few stubborn tanks that I still need to look at and fix up :)

They'll probably be made available by today or tomorrow!

Will there be plans to updated tanks from Freshwater Frenzy and Deep Freeze in similar ways?
