OK, finally nailed it!   When both stolen and blocked are rounded

Thanks for tracking this down!

I'm not sure how you mean that rounding down stolen and blocked causes time to get progressed further than expected, but I'm happy to see some more sanity checking and clamping in that code, and if it fixes your observed problems... :-)
