You didn't specify whether you bought a call or put, so it can be difficult to picture your case. I'm assuming it might've been a call option.
Generally no one uses stops on options, or trades options at market price (as far as I know) specifically because of the example you provided. Most options are very illiquid and have just a few trades per hour or per day, and have very wide bid/ask spreads, which widen even more when the stock price moves. It's not like somebody is waiting to buy your option at a fair price. This means that when you need to sell an option at market price (assuming that was your case) then you'll get the worst price possible. A market maker can set the price as $0.01 bid and $5.00 ask, even temporarily, so when you sell at market price then you may actually get only $0.01 for your option. You were lucky you've got nearly reasonable price for that option.
Trading options usually requires manual review and decision-making, or a fairly smart automated trading system, not just basic stop.
Here is an example of a very wide bid/ask, where an option seems to be worth $1.2, but if you simply place an order to sell it without using the limit price, you'll only get $0.20 for it:
