When the red sea random map was introduced a new dust particle (dust_storm_reddish) was added with a suitable color (rP18543). This same particle got used in the egypt 3v3 map. Later the same particle was used on some other maps (nubian_frontier et al) which required a even more red version. rP25496 made the reddish particle even more red to accommodate the new maps and hence breaking red sea and egypt 3v3.
This wasn't noticed in the review, but reported by elexis.
Adding a new particle dust_storm_red for nubian_frontier et al and reverting the dust_storm_reddish to be used for red_sea and egypt 3v3
