Structure limit is 80

If you need pearls go to the island in the bottom right corner cominly called herbivore island it is the safest place to live

Trust me

So I was like woah what is this present from the spring event and on my first one I got a NON BP MASTERCRAFT BRONTO PLATFORM SATTLE

I was level 52

Get a basilasaurs for the silica pearls

Build a generator on it and use turrets to make a absolute DESTROYER for sieges! U can also use rockets,cannons,miniguns....etc

If your on the island and need the silica pearls, instead of going down deep you can find silica pearls on the left side of the map right in-between the ice part and regular part of the island. There are a lot of things that spawn there though like rexes, argentavis, hyenadon, stegos, and more but if you get past that your fine

What level do you unlock this

Word

You could put loads of refining forges on the platformsadel then farm metal with an argie and an ankie the get wood with a thery it farms wood better than the bronto

You can change structure limit in settings
