The research was successful, the technology research panel reappeared and showed the technology being researched. Even so, Caleb was limited to researching military technology at the blacksmith.
This was because the number of researches was only allowed one for each technology research period.
Currently, Caleb was researching Leather Archer Armor technology. If he wants to do another research in a different technology, then Caleb must wait until the research is complete.
