I noticed that when I deconstructed the 3x tent I only got 2 tent kits back. Is this intentional? Although in real life I have on occasion lost a part of my tent due to damage or me just forgetting it in the woods, this is a very rare occurrence. It would be very nice if 100% of the materials were returned when dismantling the tent.

If that's not possible then I think another nice solution would be to make separate kits for the different size tents, and a 3x tent would take a medium tent kit and would give back 1 every time.

That's not really a bug. If you play with default settings, you will not get 100% materials back when you dismantle ANY structure that require more than 1 materials. I wrote about it in the change notes.

I took the liberty to quote your suggestion and paste it into the feedback/suggestion thread with my respond to it.

There is one known issues with the mod right now:
If you put an animal inside the tents, you cannot pick them back up. Have to dismantle the tent to pick them up.

I have no idea how to fix this. I don't know if it's affecting all animals or just some of them. I've only tested it with a bull because that's the only animal I have in my squad right now. Will try to test it with other animals soon.

I need more testing done to get better understanding of what's actually happening.

There's no protection against acid for some reason

My reply on acid rain issue from Dec 2019:

"OK, I've done some testing near Black Desert City. The survival tents DOES offer acid protection but not at 100%.

If you're not wearing any acid protection gear while sleeping in any of the tents, your health will still drop but at a much reduced rate compared to when you're outside. If you're wearing at least 10% acid protection gear, your health will drop even less, sometimes even goes up tiny bit over a long period of time. If you're wearing more than 10% acid protection gear, you will very slowly heal over time.

Conclusion: If you're going to acid rain zone, wear protective gear. Tents can only help so much."

Also, if you're not sleeping and just standing inside the tent, the protection will depend on how tall your characters are. If they're taller than the tents, they're technically outside. The tents are meant for sleeping, not as a general shelter. Vanilla tents are better for that purpose.
