Correct checkbox patch now live.
Added Admin UI checkbox patch.

EDIT: The "Change Sandbox Options" mod is probably still affected by the visible checkboxes, I will not change this. Just ignore them.

Separator checkboxes should now be invisible.

Fixed error in sandbox-options.txt that prevented the Destructive 'Never' option from being visible.

Minor horde fixes.
Random wandering is now more varied in distance.
[Random/Homing/Flee] Start Hour settings changed to use a range.

The behaviour of the time settings has changed, make sure to read the tooltips for details.
If you're using non-default [Random/Homing/Flee] Start Hour settings, you will need to reconfigure them.

Various minor fixes and improvements.
Sandbox Options layout reworked.
Wandering Zombies: Random removed and merged with the rework.
Options have been duplicated for hordes, so lone zombies and hordes are now configured separately.
New flee options.
Zombies in a horde can now be grouped by speed.
Can now control what zombies speeds (sprinters, crawlers, etc) are actually allowed to be in hordes.
Exposed the cooldown for merging hordes.
Can now have additional ticks added to a horde to reduce how frequently they move based on the amount of followers.
New option to configure the chance for wandering randomly.
Exposed the performance options.
Calm Before The Storm compatibility fix.
Randomisation is now properly synced between all players.

Sorry to everyone that is running non-default options, but you will very likely be required to reconfigure your settings.
You can use the "Change Sandbox Options" mod to do so for a single player save.
Host and Dedicated Servers can do so via Admin -> Sandbox Options.

Various fixes, improvements and optimisations.
Hordes now supported.
New "Homing Start Hour" and "Homing Total Hours" options.
New Wandering Zombies: Random configurables.
Calm Before The Storm compatability.
