Can't eat or drink enough to hibernate.

[Sooose]

Describe the bug
Can't eat or drink enough to do ursine hibernation. After eating 100 chunks of fat I verified via debug that my hunger never went lower than -15. I tried drinking as much water as I could in a similar manner and my thirst never went below -140. These numbers would quickly bounce back from their values after an hour or so making it impossible to reach the negative values of hunger and thirst required to hibernate.

To Reproduce
Steps to reproduce the behavior:

1. Eat enough chunks of fat to directly substitute body fat.
2. Drink enough water to get water intoxication.
3. Wonder where it all goes.

Expected behavior
To be able to hibernate.

So you can hibernate in a fresh version, right?

@Sooose I was unable to download the file. Could you please upload it somewhere more permanent like the Internet Archive?

Things are at least partially broken. No matter how much clean water I drink thirst never goes below -99, but this code expects it to go below -600

Cataclysm-DDA/src/consumption.cpp

Lines 1403 to 1435 in 62a01dc

	const bool hibernate = has_active_mutation( trait_HIBERNATE );
	if( hibernate ) {
	if( ( nutr > 0 && get_hunger() < -60 ) || ( comest.quench > 0 && get_thirst() < -60 ) ) {
	// Tell the player what's going on
	add_msg_if_player( _( "You gorge yourself, preparing to hibernate." ) );
	if( one_in( 2 ) ) {
	// 50% chance of the food tiring you
	mod_fatigue( nutr );
	}
	}
	if( ( nutr > 0 && get_hunger() < -200 ) || ( comest.quench > 0 && get_thirst() < -200 ) ) {
	// Hibernation should cut burn to 60/day
	add_msg_if_player( _( "You feel stocked for a day or two. Got your bed all ready and secured?" ) );
	if( one_in( 2 ) ) {
	// And another 50%, intended cumulative
	mod_fatigue( nutr );
	}
	}
	if( ( nutr > 0 && get_hunger() < -400 ) || ( comest.quench > 0 && get_thirst() < -400 ) ) {
	add_msg_if_player(
	_( "Mmm. You can still fit some more in… but maybe you should get comfortable and sleep." ) );
	if( !one_in( 3 ) ) {
	// Third check, this one at 66%
	mod_fatigue( nutr );
	}
	}
	if( ( nutr > 0 && get_hunger() < -600 ) || ( comest.quench > 0 && get_thirst() < -600 ) ) {
	add_msg_if_player( _( "That filled a hole! Time for bed…" ) );
	// At this point, you're done. Schlaf gut.
	mod_fatigue( nutr );
	}
	}

It seems things weren't broken in 0.E but got broken in 0.F. The hibernation process can start but is cut short when the player reaches 0 fatigue.

Cataclysm-DDA/src/player_hardcoded_effects.cpp

Lines 943 to 952 in 9d7ed7d

	if( u.get_fatigue() <= 0 && u.get_fatigue() > -20 && !u.has_effect( effect_narcosis ) ) {
	u.mod_fatigue( -25 );
	if( u.get_sleep_deprivation() < SLEEP_DEPRIVATION_HARMLESS ) {
	u.add_msg_if_player( m_good, _( "You feel well rested." ) );
	} else {
	u.add_msg_if_player( m_warning,
	_( "You feel physically rested, but you haven't been able to catch up on your missed sleep yet." ) );
	}
	it.set_duration( 1_turns * dice( 3, 100 ) );
	}

Another issue: there should probably be some feedback in chat when hibernation starts otherwise it may look like regular sleep

Cataclysm-DDA/src/character.cpp

Lines 10954 to 10965 in 7f33807

	if( has_active_mutation( trait_HIBERNATE ) &&
	get_kcal_percent() > 0.8f ) {
	if( is_avatar() ) {
	get_memorial().add( pgettext( "memorial_male", "Entered hibernation." ),
	pgettext( "memorial_female", "Entered hibernation." ) );
	}
	// some days worth of round-the-clock Snooze. Cata seasons default to 91 days.
	fall_asleep( 10_days );
	// If you're not fatigued enough for 10 days, you won't sleep the whole thing.
	// In practice, the fatigue from filling the tank from (no msg) to Time For Bed
	// will last about 8 days.
	}

I used debug to set fatigue to 10000 and was able to hibernate for 8 days. After 8 days I died of dehydration. Probably should have filled up on water first.
