You tryin'ta index the planet "quality-condenser" inside o' on_init, yo. Betta fix that, yo.
(not sure if it's the modlist I have. Don't have any planet mods)

The mod Quality condenser (2.1) (2.1.0) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event quality-condenser-21::on_init()
quality-condenser-21/control.lua:156: attempt to index field 'quality-condenser' (a nil value)
stack traceback:
quality-condenser-21/control.lua:156: in function <quality-condenser-21/control.lua:153>

Same issue, but without the sass.

Sorry, last moment name change messed up few things, did some changes around, hopefully it's working fine now in 2.1.1.
Haven't done much Factorio modding before
