[2.1.12] Rocket Rush lobby tiles incorrect

[KiNg626]

The rocket rush scenario lobby is now surrounded by grass instead of the out-of-map/empty-space that were there previously. Both 2.0.77 and 2.1.12 have the grass.

Thanks for the report. For 2.1.13 when playing base-only, script for this scenario will clear most of the surface (up to 128 tiles away of lobby center) with out-of-map tile which should fix this.
