Why have grout bonus when explorers never seem to find any

[procell]

Thank you for the grout bonus form prolonged searches. Only one thing wrong with it. Not one of my explorers has brought back any grout since it started. I suppose I have got a 100% bonus as 2x0 is still 0

[Shamroque]

Same here. Not one of my exploreres has brought back grout since the x2 started.

Someone at BB was laughing like a maniac when coming up with this

[amazola]

Alas, zero grout here too

[qawpaw]

6 explores this morning no grout at all

[TheVictorious]

Same, normal days, 13 explorers come with grout, during events (this is second 2x grout event do this) explorers give no more grout !

Yeah, kind of a "RANDOM" !!!!

Didn't fall for the 'double grout trap' Instead sent mine on artefact and advs as normal, got 2 rainbows and a ywc, worth far more than 30 extra grout but doubt bb understand the market that well.
Also a complete waste of a bonus period for a significant percentage of players who cannot access prolonged searches anyway.

+1 but I'm still have only 3 lucky explorers + 1x female explorer, can do artifact search, so i sent only my 10x scouts + 3 normal explorers to prolong, since I need grout, but well, got 0 until now.

same here 0 out of 22. At least now i know exactly what they bring from prolonged, i went my own business and didnt pay much attention till now.
