- In some recipe sequences (that is not added by another mod) such as (from right to left):
a) "Firebricks" with "Wrought Iron Plate" to 2x"Industrial Crucible"
b) "Bronze Machine Casing" with "Steel Plate" to "Steam Engine"
c) "Resin Circut Board" with "4xCopper Wire" to "Basic Electronic Circuit"

...first step of the sequence may be performed infinitely, sometimes taking item from depot helps (sometimes it doesn't). Progress sequence shows up (like 1/15), but progress bar doesn't.
- In case of firebricks returning back at step 6 (same as 1 and 11) resets sequence, so loop returns to step 1. It seems that happens only with recepies, where input item does not change with the start of sequence (that also applies to 1st paragraph).
a) "Firebricks" with "Wrought Iron Plate" to 2x"Industrial Crucible"
b) "Bronze Machine Casing" with "Steel Plate" to "Steam Engine"
c) "Resin Circut Board" with "4xCopper Wire" to "Basic Electronic Circuit"
