I have started to have weird problem recently. Every time I mine, and hit all the needed runes for expanding - it shows 80/80 - EXPAND NOW. Once I click on Expand now - it takes me to the explanation plots, and then - THE LAST RUNES I COLLECTED FROM MINE - VANISH...it doesn't count the runes from the last mining. Showing me 78/80 or 79/80. Bombs were taken - the ones I used. But the final runes just disappear and I have to use NEW bombs to get the runes, even though I technically ALREADY HAD all the runes needed. This has happened at least six times for now.
