Dear Ganjin staff, many of the R&D points I played in several Mirage F1C-200 games today were not added to my technology tree. Although the settlement interface did not show that there was an increase in R&D, switching to the technology tree did not increase it. I can’t help but suspect that there may be a problem with the server, but it is still the same when I restart the game. Can you help me check the issues with my R&D points? Dear ganjin staff
