Simply put: if you don't want to risk abandoned or postponed projects: don't fucking bother donating at all, and stop whining. I've seen *much* worse cases of developers disappearing or abandoning their project. If you already donated: simply cancel the rest of your payments. Who knows, maybe the developer will sometime continue his project, maybe not.
For most Patreon developers, their project is simply a hobby, which does NOT take priority over their regular job, nor over whatever happens in their private life. Very few developers manage to make enough from Patreon to actually make a living, but rather invest the donations they receive in better hardware and new assets for their renders (and $200 is small change in that regard). Maybe YOU get your assets here at F95 for free, but that's not an option for the more serious renderers, who risk lawsuits and everything, and have to get them legally from Daz or Rendo or 'Rotica. For the avarage Developer, the income from a Patreon page is nothing but a little extra to help with expenses.
What you DO risk, with your whining, is that a developer who simply has little time for a while gets stressed, burns out, and actually does abandon the project. Congratulations, you just caused that investment to be wasted yourself. Fucker!
There are currently several developers on a break for the very reason that they were about to burn-out. If you take ICSTOR for example, he failed several monthly deadlines since December (he actually no longer does monthly updates, by the way, but people seemed to ignore when he announced that), has had a ban on asking "when will the next update be" questions on his Discord for ages, and finally decided to bite the bullet and is now on a well deserved break. It took him a while to finally make that decision, and yes, it did upset some of his patrons, but it is what it is. If we want to see his projects finished, we better make sure he lives to complete it, and if possible also his next games. Whining, begging and pushing him isn't going to help get that game finished, and he's very lucky to have a team of very strict admins on his discord to just cut out all that crap.
The same applies to Aorrta: if you don't like how he handles his development, then simply don't donate. At least there's no indication yet of him to act like that Slonique idiot, who abandons every project after 3 updates for the next brainfart. Though, by now, I wouldn't hold it against Aorrta if he DID indeed abandon his project. Not because he got tired of the project, but because he got tired of the whining dickheads who most probably "borrowed" their mothers' creditcard to donate. IF they even donated..
