Press the map icon left bottom corner on your interface. If it's not the case, please inform me and I'll fix it!
I encountered a situation where a marker appeared on the map but couldn't be selected, even though there was no dialogue or cutscene—like being held captive by enemies—to trigger it. I also feel there are far too many instances where game progress stalls due to factors beyond the player's control, such as enemies dropping absolutely no ammunition or food supplies running out incredibly fast (depleting almost entirely just by crossing the map in a straight line).
First, thanks for the bug report. I will try to fix this, and would be grateful if you told me the situation it happened.
Second, Yes, I am aknowledging this problem. I will add resource gaining(collecting) methods and events on later updates, or make difficulty differences on future updates. Thanks for the feedback!
