I found many caches on leap day 2020, and Iogged them on the next day, March 1. I was careful that all cache logs were submitted as February 29. I have not found or logged any caches since that time.
In my latest dashboard, it reports that I have found 4 caches in March. However, that is wrong. All caches were in February, none in March. I checked geocaching.com, and it is correct there... all caches are logged properly for February 29.
Unsure why project-gc is picking up 4 caches and assigning them to March incorrectly.
