Silly me, I neglected to edit MySQL my.cnf to accept big BLOBs
```
max_allowed_packet=500M
```
This change allows me to run without this warning, and also makes things much quieter when saving terrain, writing OARs, and such.

no, that is as UDP thing. A packet splitting estimation math failed by 2.
that is not a issue anymore a udp packet with a payload of 1402 will still work.
