"already in Index" errors in console output

[vinnydiehl]

I'm getting the following two lines of seemingly related error output in the console:

ERROR: BID_FILE_DIS already in Index
ERROR: WIN_ADD_SQUADRON already in Index

They may or may not be harmless, but it'd be best to kill everything reminiscent of an error, eh? 😃

The problem occurs in C_Resmgr::LoadIndex() on this line. There are several spots in that method where an "already in Index" error could be printed, but both are from this line, so it's at some point in that while loop that they occur.
