Well hello there! I've got I nice juicy update for you today. Here are the highlights:

Fixes
- Sparkweed is now removed on harvest. This should make it a lot easier to gather the stuff without burning down your base.
- Charges will once again drop their item form when deconstructed.
- Detonator wire will no longer deconstruct walls it is built under.


Changes
- Sparkweed ignition is now suppressed by firefoam. The effect has a limited number of uses, so planting sparkweed in your main hallway is still not advisable.
- Chemical charges research and production has been split up. Rather than making (or buying) the generic canister, the specific type of charge now has to be produced.
- Replaced the graphics for sparkpowder and the detonator wire. The wire is now more curvy and centered within the tile.
- Gas clouds can no longer be selected. The concentration readout is now visible in the bottom left corner when hovering over a cloud.


New stuff
- Added the gas vent. I "borrowed" this one from my Gas Works project- who knows when that will be done, so you may as well enjoy it in the meantime.
- Added the refined sleeping gas. With a bit of research and the proper ingredients you can manufacture even sweeter dreams for your guests.
- Added the detonator wire crossing. Allows crossing two wires without transmitting a signal between them. Handy for complex setups.
- Added settings to auto-arm placed charges. See the mod options menu to enable.


As always, let me know what you think, and your bug reports are always welcome.
Have a nice one.
