Consistent, non-recoverable freezing when building rafts that have "bridges" to the corners of the shark's normal path. Most likely has to do with shark AI path finding becoming broken from too many obstructions. Attaching a save file I designed to exacerbate the glitch to the point where the crashing is extremely consistent (frequently within 10 seconds, occasionally within 30, never takes more than 60 seconds to crash)
Save was made exclusively on V1.04, no file editing or glitches were used to get the game to this state

I confirmed the same thing happens on newer, smaller saves that only have bridges built to those areas, but was unable to keep a save file due to the consistency of the freezing.
EDIT: Just saw V1.05 was released. Checked the same save file using V1.05 without changing anything else, and it still happens.
