TL;DR: This adds so much to a modded server, with much potential to allow players to play for new benefits in-game.

Usually I take a month before writing up a review to see the in's and out's of the plugin, but with this one I'll make an exception to that rule.

I have just got this plugin today, but everyone loves it. I use another plugin called EpicLoot and with that it's got a currency that's a skinned version of blood. With this plugin, I'm able to allow my players to spend that currency on upgrading their furnaces (and refineries). 

This has increased the value of that currency, and players had some spare just going to waste anyway.

The biggest thing for me (honestly amazing) is that the upgraded furnaces keep their levels, even if you use /remove to pick them up! 

If you use other plugins that have a currency with them, if you think that you'd like to use that for other things, then this plugin is for you. The developer is super active, and responds to messages in no time at all. In fact, I think Yun is the fastest dev to get back to me ever haha!

I asked a question in the support section on April 10th and have not received a reply. On April 11th, I provided information about bugs that need fixing and errors coming to Rcon. Our goal is to help developers and ensure that plugins work as well as possible, but there has been no response for 17 days. The auto fuel and auto split features in the plugin do not work properly with StacksExtended and the umod stacksize plugin, causing incredible spam in the console. When the server starts, at least 50 lines of error code appear. I fully believe these will be corrected and I understand that development takes time, which is why I waited patiently for more than two weeks. However, at the very least, they could have said something like, "Sorry, I haven't looked into it yet, but I will attend to it or I am adding it to my plans for next month." It shouldn't be hard to say that! Yet, there has not been a single word in response. When I look at the seller’s profile, I can see that they log into the site every day. Unfortunately, it's disappointing.

Edit 4 May 2024

The seller apologized for personal issues and delays, and also fixed some errors.However, there are still some features not working.

The Auto split and Auto fuel features are giving errors with StacksExtended.
"[Furnace Upgrades] The CanMoveItem hook was unsubscribed due to conflicts with the StackExtended plugin"

If those are fixed, I can give a 5-star rating.

Have a good day
 

Honestly, I've been waiting so long for a new plugin for this, and it's perfect! Easy to configure, and the dev is clearly on top of his game, fixing things within hours!

Thinking of getting this plugin? It works like a charm, we love it and our users love it too!

If you run into any problem, Yun is there 110% to make sure you love and benefit to the fullest of his product. 

If you need furnaces upgrades this is THE plugin YOU NEED! 

Enjoy.
