Weird Eeprom Problem

[LianneJaguar64]

I don't know if anyone else has ever had this problem, but I just popped in my copy of Hover Strike, but upon getting to the menu and pressing B to load, I'm asked to select a difficulty, as if the game has no save data stored (I was on the Level 4 missions). So I soft reset, and tried again, to the same effect. Then I hard reset, same again. Assuming that the Eeprom had failed, or at least had an error and deleted the data, I played a mission and saved, then soft reset. Back to having no data. So I took the cart out and put it back in again, powered up again and hit load, and there is my save file again, on Level 4! I assume there was something that was blocking the pin connectors, but has anyone had something like this happen before?

The save EEPROM is connected via pins on the cart connector just like the game ROMs, so it is entirely possible for it to not get a good enough connection to work.  It isn't included in the initial boot checks.
