Orangeade from Seasons doesn't seem to increase badge point for sewing and pottery. The enthusiasm icon for cuisine appears above Sim's head, but badge point icon does not. It is possible that they gain badge point silently without displaying icon, but I don't think so.
I'm not at all surprised, it is expected that features introduced in one EP will not work for another EP. But I'm annoyed, as it takes ridiculously longer time to earn even bronze badge for sewing and pottery. (And I thought cashier badge took too long time
) They made it deliberately harder so that we players are forced to get Sims into Zone.
Unlike TS1, I feel that EPs for TS2 are not fully integrated into a whole game. Back when TS1 days, Makin' Magic had a spell only unlockable for players who had SuperStar as well. Instant Fame spell required black rose, which can be only gained from Obsessive Fan for superstar. Some cake and spell recipes in MM required ingredients from Unleashed. Now, it would be "unfair" for new EP to include a feature that required previous EPs, so EAxis denied juicer for FT badges, suppressed Uni career LTWs, and so on. Stupid, and bad marketing decision as well.
