Action E force-activation not working

[DaleStan]

TTDPatch a66 reports that "newgrf/alpinew.grf has invalid sprite #6 (code 17/6)", but I do not see the problem with that sprite.
(17 is "Attempting to deactivate already active GRF file")

For your convienence, here's the first 8 sprites:

Code: Select all

 0 * 4 	 EA 01 00 00
 1 * 9 	 07 8B 04 05 07 02 0A 02 01
 2 * 17	 0B 03 1F 00 "2.1 alpha 52" 00
 3 * 6 	 07 85 01 00 59 01
 4 * 17	 0B 03 1F 02 "newhouses on" 00
 5 * 6 	 07 92 01 03 00 01
 6 * 6 	 0E 01 "mb" 07 00
 7 * 101	08 06 "mb" 07 00 "AlpineClimate V0.1 15.06.05" 00 //...

There's also problem with Toyland2Mars.grf (Mars climate).
it says "newgrf/Toyland2MarsW.grf has invalid sprite #4(code 17/6)",
I gess it's the sane problem...
