Arena mode: Failed to create monster, env.grid: deep_water

Hello,
I was playing a bit with the Arena mode until I encountered a “fatal error” screen.

The following input (for example):

8-headed hydra v 2 electric eel

Gives this error:
“Failed to create monster at (33,34) env.grid: deep_water”

This isn’t the first time I tried it, however. I tried some other inputs with electric eels prior to the example above and they all seem to cause this fatal error, with different numbers in parantheses but the same “env.grid: deep_water” text afterwards. This seems to happen with any input containing at least 2 electric eels, but I haven’t tested a large amount of different inputs to say for certain.

Is this a bug?

Dungeon Crawl Stone Soup version 0.31.0-12-g77e489cdc1 (tiles) (Android, version code 30 from F-Droid).

Thanks

I just now noticed that I’ve got a crash report. Here:
