From what I read live, unstable WW1 ordnance is still being ploughed up in Belgium, in significant quantities. It gets left in piles by the side of the road for the Belgian army bomb disposal guys to deal with, apparently!

During very cold winters the sea in this area freezes hence why the Hetzer was so far from the shore line, it’s thought that it was lost during a retreat.
Here in Belgium it’s illegal to go relic hunting but it’s still done on a regular basis as is the surrendering of WWII weapons usually held in barns and kept just in case of another invasion, after WWI when the troops left the trenches there was a vast amount of live ordinance left behind this was merely thrown back into the trench buried and forgot nearly 100 years latter it’s deadly and just waiting to be disturbed
