Hunk?

Delete all Nodes and anything of that stuff from your map and download the package again, jeez.

If i open Torlan special map from wormbo, it is there. If i copy that node to s8 the option disapear.

Well, then just don't use that map since it's probably an older release.

Do it the usual and better way: Download the .u-file, then write in the command line of the editor
obj load file=OnslaughtSpecials.u package=myLevel

You probably need to write it twice in order for it to get recognized.
And you also should uncheck and recheck "Show placeable classes only" in the ACB in order to refresh it.

I didn't myLevel OslaughtSpecials.u for ONS-Torlan-Specials because that would make testing very complicated. It looks like there's some more work involved when updating a myLevel'd package.

I recommend selecting all the special actors in your map, cutting them to clipboard (paste them to a text editor so you don't lose them if you accidentally override your clipboard content), save the map, restart UnrealEd, open the map again, myLevel the new package and paste your actors back to their original location. Note that for some reason "original location" means 32 units up, right and forward. Before pasting you might want to set the grid to 32, so you can move all actors by one grid unit down, left and back.

Thx for reactions, it -still not work in any map, i still got the previous version installed i think. Only ur example map got the new nodes.

What works: I see them in actor class. But the wrong one.

Here is a screen:

Well, as I said already: Go download the stuff again from Wormbo's site, that way you can be sure that you have the latest version.

You don't need the Torlan, just myLevel it from the package as I told you above.

I did what u say, and i see them now in actor class. But still other version...

Ok, let's try that again.
Start UnrealEd and load your map. Select all OnslaughtSpecials actors(nodes, cores, node lockers, ForcedDirVolumes, etc.) in your map and do Edit -> Cut. Paste them into Notepad so you don't accidentally lose them. Now save your map and close UnrealEd.
Start UnrealEd again and open your map. Verify in the Actor Classes BRowser than the Onslaught Specials are not loaded. Now myLevel the new OnslaughtSpecials.u package. Refresh the class tree in the Actor Classes Browser as Crusha explained and verify the Onslaught Specials are there. If not, try myLeveling OnslaughtSpecials.u again, sometimes it only works on second attempt, no idea why.
Now set grid size 32 (for easier location fixing) and paste the actors back into your map. Rebuild and save.

Ok thx, i will try that, but i don't understand why in my map, if it also don't work in other maps?
