[3.84] a very large spring

[Plotinus]

Kari, a migrated character, is visiting a village which on the shore of a lake. The parts of the lake that overlap the village have been changed to a giant spring. I can provide a save if needed.

[Sami]

Ah, it must be so that for migrated villages all the water tiles within the village area are converted to spring water. No need for a save, will fix.

(As a curiosity large spring based ponds/small lakes do exist and in regards to their water origin they can be still considered springs.
 But yep, in the game we've got only small ones.)
