Slow and rigged

This game is really fun and addicting but it takes forever just to load anything . And whenever I do quest I always try to go for the support items and In the end It says that I obtained them but when I go and check my items its not there I should have like 1000s of those capsule Corp drinks already. Lastly the training item feature is dumb when I accidentally click on the wrong item I cant just unclick it I have to exit back and restart it again pls fix these problems
