after gathering the resources and settlers needed to make over 100 longbow men, i produced them. after there completion, I was making the other troops needed to attack Wild Mary. while they were in the oven, i turned off the game. when i arrived back to send the units attacking. To my surprise the longbow men were gone and so were the settlers i used to make them. The raw materials were back except for thr settlers and the resources used to make them. This needs to be solved!
