A Dense Goblin

I'm making a WAD for Doom II which will be somewhat of a total conversion mod. I have imported custom weapons and I have a custom weapon replacing the pistol slot, with a KEYCONF file, the code for which I will paste below WEAPONSECTION "CROSS" SETSLOT 2 ImpalerXBow I'd like to know, is there a way I could set this weapon to be in the player's hand automatically in place of the pistol when warping to a different level with the IDCLEV or WARP commands?

I'm making a wad for doom II, and i decided it would be a cool idea to use the Nazis found in the secret levels, but I want to make a few modifications to them, first. I know the basics of modifying monsters (using slade), but how would i load it so that the enemies show up within the level data on slade?

Hi. I'm making a doom level and while working on it I decided to try and add some custom music. The music worked . When I was doing this, I had Slade and GZDoomBuilder open, but then I took a break. Later, when I got back on, I decided to change the MIDI, but in a stupid lapse of judgement, I had closed GZDoomBuilder but not slade, and I saved the version of the level that was on Slade, thus kind of undoing a lot of progress in the level's geometry. I don't want to spend 2 hours redoing it so is there some sort of recovery feature?
