So, what exactly is going on with the Claude usage limits?

I'm extremely new to AI and am building a local agent for fun. I purchased a Claude Pro account because it helped me a lot in the past when coding different things for hobbies, but then the usage limits started getting really bad and making no sense. I had to quite literally stop my workflow because I hit my limit, so I came back when it said the limit was reset only for it to be pushed back again for another 5 hours. Today I did ask for a heavy prompt, I am making a local Doom coding assistant to make a Doom mod for fun and am using Unsloth Studio to train it with a custom dataset.
