Your sample size is statistically insignificant.Problems????
I have been using the County Treasurer process to get a doe license for over sixty years and never once had a problem of not getting my license before I needed it. Never once had to call a County Treasurer to straighten out any problems.
I only used the on line system to purchase my regular license twice and one of those two times turned into a nightmare of phone calls and over six weeks without receiving the licenses I had paid for. It even cost me more to order on line, so it was even a nightmare I had to pay extra to get.
Nope I will never again buy my licenses on line if there is any other option available. I'll stick with, and much prefer, a 1950's system that works correctly over any new system that doesn't work correctly half the time or for that matter even a significantly smaller percentage of the time.
