Very nice! You should upload it on Spigot as well, they have a premium resources section.

Tekkify is now running a brand new, fresh server which launched yesterday. The OP has been updated to include all new information. http://tekkify.com/play http://tekkify.com/

You need to remove Java 6 or set Java 7/8 as the default.

​Blightfall is having an official release next I believe.

You can browse Bukkit plugins on the dev.bukkit.org website or SpigotMC resources section. To run plugins you need to run Cauldron or a variant such as KCauldron. tcpr.ca/cauldron

Probably using Java 6. Pastebin the crash from the crash-reports folder.

I can see the appropriate builds here http://solder.game-gumba.de/TechnicSolder/public/api/modpack/game-gumba-keinelustmehr - But I cannot see them on the launcher. Your modpack page shows version 5415 for me. I'd recommend hopping on IRC and contacting GenPage. However as a quick note - Your web root should be the public/ folder, not whatever folder TechnicSolder is in.

What is your Solder URL? It might also be worth joining IRC, there are a few people available there who can help you with any Solder issues. Feel free to ping me (Nentify) if I'm on, or GenPage (current maintainer or Solder) if he's available.

What are you looking for in a modpack? You could always have a crack at making your own with mods you enjoy, and perhaps take ideas from other modpacks that you enjoyed. Maybe the next Tekkit update will be a little more interesting. From what you described, B-Team seemed like a decent choice... Honestly at the moment, there aren't many packs that I would go "this has a really cool, fun and unique play style" at, even my own pack. I've been working on something on the side which has a bit more vision and direction and provides something a bit new, but haven't had a lot of time to work on it.

​What version of Solder are you using? If the builds are private or hidden, that could cause issues with them showing. If you're able to select the pack in your launcher and it crashes when you play it, you need to look at the crash reports or logs for your modpack, not Solder. If a file can't be downloaded, you need to view your Technic Launcher logs files to find out what mod is causing the issue.

​Duplicate ID of what? It looks like some sort of entity ID conflict or something, but I'm not so sure. But be worth contacting the mod developer.

To expand, your build should be available in the Technic Launcher, it's likely just broken. The errors in the console or logs should tell you why. Amaxter is correct though, the platform website itself has a 1 hour cache, so updates will not be reflected on your modpack page immediately.

Tekkify 1.7.10 is now live! New modpack, servers, website and more! Just update your modpacks on the Technic Launcher: www.technicpack.net/modpack/tekkify.2607

I'm also experiencing similar delays, although I'm pretty sure it didn't occur in previous builds. Some new features such as optionals like @disconsented mentioned too at some point would be really useful as well.

Install Opis and MobiusCore on your server and client, and use those to see if there are specific tile entities causing the TPS reduction.
