Update #4

Bug Fixes

• Fixed bug where random start day could be 0 and therefore virus would never spawn.

Vaccines

• Added vaccine immunity simulation
• Currently, vaccine coverage will grow by 0.3% per day which can be increased by restrictions (+0.1% with restricted travel, +0.2% with mandatory masks, +0.3% with lockdown - for a total possible +0.9% daily). A more realistic system for this will be added in future.

Restrictions

• The effect of restrictions will now be slowly eased in over the course of 7 days instead of applying immediately.
