Now backported to 1.19.4, please report any found bugs! 1.19.2 is probably the lowest I will backport, as any lower versions remove animation from the flags.

A new massive update is out! Every flag has been revised and looked over, spotting for mistakes and implementing new changes where necessary!

Added: 

• International Maritime Signal Flags [51]
• Marvel Country Flags [23]
• Racing Flags [12]
• Ecology Flag - Happy (Late) Earth Day!
• 2 New Tools: Animation Adjuster (changes animation to a still animation, not compatible with Pole Adjuster). Flag Enlarger, change flag size from 1x to 2x, 4x and 12x (very large, do be warned). Also not compatible with Pole Adjuster, as well as Side, Top and Still animations (only works with default idle animation)

Changed/Fixed:

• All civil, state, naval, variants, etc. have had their name format changed, now instead of having brackets beside the name of the flags, e.g. "Flag of Albania (Civil)", the "Civil" part will now appear as a blue subtext, e.g. "Flag of Albania" with a subtext "Civil".
• Similarly unofficial/proposed flags have an orange 'warning' subtext 
• Alternative names are put under subtext instead of square brackets, e.g. "Flag of the Sahrawi Arab Democratic Republic [Western Sahara]" has been changed to "Flag of the Sahrawi Arab Democratic Republic", with a yellow subtext reading "Other Names: Sahrawi Republic, Western Sahara, SADR"
• Flags with ratios 11:6, 4:3 and 7:6, now have their 'flat' variants fixed, as previously they used their closest available ratio
• Updated Chatham Islands and Cocos (Keeling) Islands flags to their most up-to-date version [Chatham Islands now uses 2:1 ratio, previously 3:2]
• Flags of Duchy of Aquitaine, Lorraine and Normandy have been moved to French Regional Flags
• Fixed Slovakian Region Flags being in wrong order in creative tab
• Baker, Howland and Jarvis Island are now all separated in command line (still give same flag)
• In 'regions' command line, changed UAE and USA to unabbreviated form (usa -> united_states_of_america)
• Saudi Arabia flag, as well as its civil flag, now have fly side to left to be more accurate to actual flag. Additionally, icons changed to match this
• Rigged flags now explode when activated by redstone
• Moved flags of United Korea, Earth and FTR to 'misc' section of 'other' flags
• Made minor adjustments to following flags (including name changes, minor mistakes, etc.): Australia (+variants), Anguilla (variant), Chuvashia, Comoros, Sudan, Falkland Islands (civil), Fiji (civil), Formosa, Christmas Island, Aruba, Curacao, Bonaire, Akrotiri and Dhekelia, Azad Kashmir, Bangsamoro, Cambodia, Gagauzia (+variants), Kyrgyzstan, Latvia (Naval Jack), Uruguay (Treinta y Tres Variant), Navassa Island, Norwegian Antarctic Dependencies, Papua New Guinea, Saint Barthelemy, Saint Martin, U.S. Virgin Islands.
