Mr Fantastic's Imaginaut is triggering itself

I’m not seeing Mr. Fantastic’s Imaginaut repeater causing the random effects it’s supposed to create, like creating SAP tiles or charged tiles. Instead, every time the repeater goes off, it does the animation and creates a duplicate repeater as if I’d just fired Imaginaut again. Then both of the resulting Imaginaut repeaters create more Imaginauts until, within a short time, all the black tiles on the board have been converted into Imaginaut tiles, but they don’t do anything useful.

I was able to complete Mr Fantastic’s Imaginaut quest in record time since I was ‘firing’ it a dozen times per battle, but I don’t think it’s supposed to be a self-replicating effect.

I also just experienced a bug with Imaginaut, but not quite the same. For me, when it reached 0 it did nothing. Then the next turn it went up to 2 again.

One month later and this bug is still present. Mr. Fantastic (Reed Richards)'s Imaginaut is only spawning new Imaginaut Repeaters. Instead of creating various friendly specials, it is only self-replicating.

It was broken for the entire Fantastic Four special event. That’s just special, guys.
