I think most of the achievements aren't working due to the steam client crossover? I'm not fully certain but since that client can only watch your belt that might be the problem. If not then it's probably due to them needing more server space, remember each aspect of the game including ranks, belts, achievements, tc, items, market - all these have to be funded and with less and less people buying TC from the official store and buying it off the market for a cheaper TC - £/$ then hampa and nabi studios isn't getting funded enough for servers + wages. #ItAintFree
