Probably not worth the effort, but if you want to get rid of the remaining spider models that are baked into zone files, I made a little program for that:
https://dl.dropboxusercontent.com/u/...20Squasher.zip
1. Download the above
2. Unzip it (it's a folder with some stuff in it)
3. Put the folder (with its contents) in the EQ folder you want to remove spiders from
4. Open the folder and run EQ Spider Squasher.exe
5. Should take around a minute, will show a popup with the number of files changed when finished.
