Everytime I try to export structures with hoppers, furnaces, spawners, traps, command blocks etc. in it, I get an error message saying "An internal error occurred while attempting to perform this command". I don't get this error with empty chests, though.
This is the command I'm using: /exportbo3 name --includetileentities
This is the error I get in console: http://pastebin.com/XjtGfyj2

I'm using spigot 1.10.2 version Spigot-1e4dd71-5e5cf84, build 152 of terrain control and the v1.6-SNAPSHOT of bo3 tools (rutgerkok suggested this version on the TC forums).

Try using the versions Rutgerkok mentioned on the forums, they work with everything but tileentities.

Its not only with the tile entities. I cannot export any bo3! I get the same error. BO3Tools are outdated (using tc 2.8.2 snapshot). Rutgerkok please?

*hint: It shows the error in-game, but the file appears in the world objects. When you browse it though there are no blocks saved in the "Blocks" section

The only way to create a bo3 is to write the blocks down manualy. Useful for small objects but almost impossible for big structures

As I said, use the versions (tc and bo3) mentioned in the post. They work except for tileentities.

i already have tc 2.8.2 snapshot. i always use the latest dev builds.
the problem is at BO3Tools not tc

I'm sorry but did you even read my post or the forum post?

"I'm using spigot 1.10.2 version Spigot-1e4dd71-5e5cf84, build 152 of terrain control and the v1.6-SNAPSHOT of bo3 tools (rutgerkok suggested this version on the TC forums)."

i ve just noticed, you said 1.6 snapshot... the build 1.6 Bo3 had no name, but i found it
Yep it works now

Indeed, it doesnt save entities inside the chests

You are talking about downgraded versions. I currently use the latest versions. these files have a name. Can you tell me which versions are you using. I really dont want to downgrade and mess up with everything else and cause error shutdowns and server kills just for the bo3 to work.
tc: 2.8.2 Snapshot
bo3: 1.5

Hey ZoefyC, Rutgurkok fixed the bugs.
Here is the fixed version:
