what happend here? first time i seen this problem. this was actually my final save a my map is complete..(lol)mp_edgewoodhospital was the map and then i changed it to a daytime setting save as mp_edgewoodhospitaldaytime.( no problem with the world spawn settings),,, but i added a couple more decals and now the decals are saved in the editor but not after i compile.. never had this happen before

It means your map is not compiling anymore. You're basically playing your old map.
Please post your compile log, so we can figure out what is causing it.

How to get your compile log:
Right click the black window.
Select all.
Press enter.
You can now paste it in a text file or post it here.

i found the problem ....too many map materials exceeded the limit. problem fixed. compiled with no problem.. i should have checked first before i posted.. thanks for you help anyway.........

yea i once had that problem and the max decals u can have overlapping is 8 anything more than that ur map wont compile the new stuff....lol. so i had to go back and take out a few of them out and then recompiled and it work fine
