Can't place build in my fortnite map (UEFN session)

Summary

I have recently made the fighting area in my map bigger and longer in height, meaning i had to move the floor of the fighting area down. I made sure that i had the snap link thingy on so that the grass floors snap to fortnites grid thing. But now i just can’t build. I have builds, builds are turned on!

i have the same problem, can someone help me?

The issue is this

The building system works on the world grid system. Imagine a grid in your map that is invisible and is filled with 1x1x1 squares. The build piece needs to align with this in order to anchor itself to the world. if you place a gridplane at 0 z height itll work as this is aligned with the world grid then i think any height in increments of 512 i believe will also work but you moved the grass and its not within this tolerance hence the issue. You can either move the grass back to the standard grid and builds will work or you can create a bp prop and within the settings you can setup the system so you can build from that height

There will be yt vids on this i would assume
