When I attempted to capture a neon cuckoo bee, the server crashed with the below error. Is this version of production bees still 1.16.4 compartible? I couldn't get GD Launcher to detect the update, so I manually loaded, which made me think it wasn't really marked as version compatible for what I was trying to load it in.

It's a beta version that's why GDL doesn't show it to you unless you tell it to get beta version. Which version exactly are you using?

Using 1.16.5-0.6.4. I've got a new world and just started out. I was able to capture Mason and a few others without issue. Maybe lucky on those.

I have some changes to the BeeCage in dev, I'll upload those. It could be something that happens if you have only 1 cage in the stack, this is what I was working on fixing.

Cool, I was down to 1 cage when it happened. I can test and let you know.

Uploaded it now. Hopefully it works as I don't have much time today for testing it.

That patch looks to have resolved the issue with a single cage in hand.

BTW, on the beta not showing in GDL, I've got it set of alphas since a lot of mods stay in perpetual alpha/beta state. I don't have any issues seeing the 0.6.2 or 0.6.3 beta versions. Just 0.6.4 and 0.6.5 stopped showing up.

Thanks for the fix.
