I made a post but it got moved to bug report even though I had a bug post over there about it.
This post is to try and see if others are experiencing the same issue.
Have you been able to find the same recipe more than once? Some people said it could be Basil timer for doing the same gate, but I was just curious if some of you wouldn't mind paying attention to the recipes you bought previously and see if you come across them again.
UPDATE:
I think we got it figured out roughly. There is a timer on new recipes bought from Basil, and each Basil ( T1, T2, and T3) has independent timers it seems. Been running with 2 alts as control elements for the testing and got a lot of feedback from friends to help confirm it. Not sure how long the timer is but it seem to be less than 24 hours but more than 2 hours, can't narrow it down due to all the luck involved in finding the same recipes again ( extra variable we can't control). Having the recipe in your possession or not wasn't the factor, we just had to wait for the timer to expire before the char was able to see it again.
So again thanks for all the feedback.
TL;DR There is a hidden timer for basil recipes based on Tier level.
Yes, this showed up in another thread. I can't find it right now. Some thread arguing about whether having these new recipes be Basil-only was a good idea.
