To your original question:
Readme.txt is only the information and instructions file of the mod. If you overwrites it with another readme of another mod, you will have the last readme added...Only that.
No readme file can produce any conflict between mods and it isnīt a cause of crashes.
If you install and uninstall constantly mods with JSGME, some "residuals" of the mod, not properly uninstalled, can remain in the data folder and that can create a conflict. Do you experiment some crash in JSGME when installing mods?
Do you use the 4GbPatch? Your load of mods isnīt important, but if your PC havenīt capacity, that can produce a CTD.
Best regards.
