on_init calls reset_global_poles()
but in reset_global_poles the length of max_consumptions is 0 (no entries).

I found this after adding the mod to a saved game and wondered why the small poles are not exploding :D
It turned out that the reset_global_poles function operates on a empty max_consumptions table.
I hacked it working by adding line 363 to 366 after line 344 in control.lua.
Then it works and global.poles contains the poles :-)

Thanks for reporting and diagnosing this problem! I guess that I'd assumed that on_load was always called whereas actually it isn't called when on_init is. The broken behaviour fixed itself by saving, changing any startup setting or the list of installed mods, and loading.

Fixed in 1.2.0.
