QUESTION ABOUT WRACKS AND LIQUIFIER

stupid question since the GW APP is so full of bugs:

for Wracks, the Codex states that for every 5 models in this unit, one model can have a Liquifier Gun.
For the Acothyst, they state that he can have a liquifier gun (so a total of 3 in a unit of 10) but the app claims that i have too much liquifier in my unit.........is it a bug or there is something i don't understand right?

Thanks for your validating / informing me

A unit of 10 models may give 2 Liquifiers to WRACKS. Asside from that, the ACOTHYST may get a Liquifier.
So yes, I'm pretty sure you're right, and you can have a total of 3 Liquifiers.

Correct

thank you guys for confirming this
