Canon EF 50mm 1.8 with Canon Rebel G 35mm camera shutter speed issue

Hello,  recently I bought a brand new EF 50mm lens to pair with my Canon Rebel G film camera.  The Camera itself is in mint condition .    I was out today taking my new lens for a spin .   The weather was overcast with some slight drizzle.   I was shooting in AP mode  at f8  with 200 ISO  Kodak Gold .   Occasional the camera would set the shutter speed to 30 seconds.   I would turn it off and then it would be fine for a couple more shots but then it would happen again.   I did put in auto and immediately called for the flash on the shots.   

Now I undertand on an overcast day the camera will call for a slower shutter speed but 30 seconds seemed excessive.   

Is this normal?   I  fear either some rain drops might have gotten in a started wreak havok, though it was only a slight drizzle   or 2.  the  50mm lens wasn't syncing well with the the Rebel G  or 3.  This is the first sign of this camera starting to fail.

thanks for any insight

A Rebel G film camera DOES NOT HAVE menus like a digital camera does. There IS NO "Reset" function.

yeah that is always the risk,    It was advertised as Mint condition and lightly used,   it came in all it's original packaging and box  and it certainly looks like it has never been used, no scratches nothing  it really was in mint condition.  that was about 2 years ago.   I have always used it in auto mode and never a single issue.  I've recently wanted to start to get more into manual controls and decided to start out with Av .     I'll keep playing and testing and just hope this is a one off.

I understand,  but something is definitely off in Av mode even at f8 the camera  calling for 30 seconds is way excessive,  it wasn't that dark at all, just more of gray day around noon even with a 200 ISO film .
