There are still some lasting problems with these. The previous problems of sticky 'nade not showing as owned and the repair directive not working have both been fixed. But I now have 72 prox mine kills showing in my stats but none on the directive. Also I have tank mines (not used yet) but they do not show as owned in the directive. There is an oldish bug report which I have voted for but it is still saying DBG needs more information. I posted a ticket and the response included the suggestion that I raise the issue here to see if anyone on the forum has information or suggestions.
