Moduals vanish(voided) when switching between the mode of fueling. Maybe just make them permanently only use fluid/gas input; don't really ever use canisters it just over complicate-it, especially since inserters don't seem to be able to remove the empty canisters.
Hydrogen furnaces placed via blueprint in the hydrogen fluid mode won't take in hydrogen. Have to cycle them through the modes to get them working(how I found out about the first bug). also very annoying how changing modes resets the orientation.
P.S. Thanks for fixing the fuel balance issue from before.
