Note: This is NOT the rewards eggs. These three eggs are from critters that I found out in the wild, fed, petted and looked after until they were ready to drop an egg. Only it's not letting me transfer any companion eggs, regardless of the source.
Usually on expeditions, if I come across an interesting or cute critter that I want on my main save, I'll get an egg from it and, after the expedition has ended, pass the egg(s) to my spouse (we always play expeditions multiplayer together), reload into my main save and have him transfer back to me.
With this expedition and the new transfer mechanics, we were celebrating not having to do the giving each other stuff and reloading to transfer. Only, I can't transfer eggs that I got from creatures along the way. We started the expedition from our main saves (to see what that was like) rather than starting a new save like we used to.
We also tried the method of me passing the eggs to spouse, swapping to the main save and then spouse giving them back but that doesn't work because as soon as he tries to join my game, it starts the expedition for him again.
Is there any way I can transfer these? Or is my only recourse to back track through a heaps of systems to the planets I got these critters from and get the portal glyphs to then travel there after I've swapped back to my main save? :/
EDIT; I also just noticed I can't transfer the Memories either - I usually like to keep these sorts of things in storage containers as 'souvenirs' of expeditions :(
There's a hard limit on how many eggs you can have in one save. They probably restricted transfer for eggs from expeditions to avoid going over this limit.
It would be worth raising anyway, as they may able to allow the transfer but not allow collecting them in the main save until you make room. Or allow transfer when the main save is below the limit.
But eggs != companion though. You can have an egg and just not allow hatching it if you dont have a free companion slot. How does it handle you redeeming a companion egg from expeditions or twitch rewards when all your slots are full. Presumably it functions exactly the same.
I feel this was more of an oversight than anything else
You would think so, but it won't let your companions lay more eggs when you're at the limit. This is separate to the companion slot limit. I assume it doesn't let you redeem eggs when you're at the limit either.
If I had to guess, eggs require more data than a typical inventory item, due to the complexities of creatures. They're probably implemented differently with some hacks to make it work, and limiting numbers is the simplest way to avoid complications.
That could well be it. Although I doubt it would require much data. We are talking about significantly less than terrain editing
The game has a lot of strange limits like that. Like allowing only 10 Message Modules, where Minecraft worlds allow infinite signs (or at least such a high number that, when you search how many are allowed, you can't really find an answer). Or only allowing you to store 16 Personal Wonders, even though they're just stored seed values, which are also about as simple as storing a text string.
