[Stuck in Excavation - What do I do?]

Same exact thing happened to me. But i think my game bugged. After i would complete an excavation site, it would just keep giving me more. it would not stop. i ended up doing around 7-8 excavation sites and i had no choice but to abort. This really made me unhappy as i got a lot of good loot. Also, the green marker pointing to the end would just appear at the very edge, not even on the map area. FIX THIS GODDAMNIT
