heya, the grid not loading is because your server FPS is too low. if the grid never loads it's most likely because of the last Rust update with swinging vines.
1. Run this command in the server console, and the grid will load.
2. Restart the server if RustEdit (even if using a procedural map) has not been updated to 1.0.54, or manually update from from https://github.com/k1lly0u/Oxide.Ext.RustEdit
3. Make sure you've done both #1 and #2 even if using a procedural map
4. RB already spawns in the jungle biome, once the grid loads.
5. Adjust height in the profiles to spawn bases in the air. Height Adjustment Applied To This Paste is a good option to apply to all bases in that profile. or you can modify them 1 by 1 in the paste options below where you list each base individually.
