Scan aborted with NoneType has no attribute "read"/"tell" when parsing relics

[kel-z]

I honestly have no clue where this error might originate from in the code. I was using the release version so I wasn't able to get a full stack trace--it must have something to do with relic_strategy.py since it aborted in middle of parsing the relics. It happened to me once and then never again.

added a stack trace to the log for v0.6.2

if this happens to anyone, please comment with the stack trace here

Scanned with +100 delay on both nav and scan speed with the wall of the Astral Express parlor car (dark grey) as the background

Thank you! I finally see where the problem is coming from. Looks like one of the images used for template matching can fail to load for some unknown reason, which results in attempted function calls on a 'None' image. Probably suffice to add guards to check if the image is loaded to prevent this error from happening again.

Awesome. thank you for all of the work you do on this. I find the scanner and optimizer to be extremely helpful/valuable
