On one of our servers we use the foundation limiter.
The setting was set to 125 max foundations and a scan range of 35
a player had built a huge base surrounded by a wall both of which I suspect used the max foundations permissible.
When another play attempted to create a raid base and placed a foundation all players were kicked from the server with packet flooding.
I restarted the server several times until the problem was identified. I changed the scan range to 20 and restarted the mod and the player was able to place the foundation without players being kicked.
