You should always store a backup of your BF1942 install with all it's mods.
This is my (/mods/bf1942/Archives/Objects.rfa) file. Remember that this is the 1.61b version so if it does not work, then patch your BF1942 up to that version. See the attached file.
My recommendation is that you shouldn't be changing anything in Objects.rfa until you get enough knowledge. Try solving it by creating a patch file (objects_001.rfa) or making a map patch file (bocage_001.rfa). I recommend making a map patch file, that way you only screw up one map at a time and it can be removed at any time.
Let me know if there is anything else I could help you with.
