Kid stop lying, you clearly did not memorized the event cycle. Like HolotheWiseWolf said, events are on a 4/5 week rotation majority of the time. You can complain after that amount of weeks if the event does not show up. Seriously, too many beggar f2ps not wanting to work and save for their coupons and want stuff for free.

Then don't assume the event is automatically removed when it hasn't shown up for at least 4/5 weeks. You worrying isn't good for the health of our forum. We don't need this behaviour.

But you know these players aren't going to complain when the event isn't generous

Based on your forum account, you have been playing this game for at least 2.5 years. Honestly, you should have learned the event cycle by now. Make sure you do since we don't need more of these posts asking for an event that already showed up within the 4/5 weeks.

Most events show up at least one month OR 4/5 weeks or one month. If you have played attention since you started playing back in 2017 (at least), that's how it goes. Veterans know this and aren't worried. If Oasis decides to repeat the events more than once in a month, its fine but you shouldn't freak out if they don't. You should also look beyond March to make you argument valid since past March 2020 (Mar 5), the last time Firework Festival showed up was Feb 13, which is 4 weeks apart.

Don't listen to people who aren't willing to learn the game trends and just spam the forums with suggestions.

The key word is "recently" for the 3 week cycle. OP just assumed the 3 weeks for entirely since they did not know about an event showing at least once a month or 4/5 weeks. I feel like it is best to correct them to avoid misinformation. I corrected them and they didn't acknowledge it, It's their job to understand that and not ignore it. If you have to be rude to make people understand, then so be it.
