0.9.81.1b Fixed the weapon range issue

0.9.81.1b • Fixed an issue where weapon range became shorter when mounted on low-profile vehicles. Previously, weapon range dynamically changed based on hull height, which was confusing. Now it has been standardized — the same turret will have identical range whether mounted on a RC Maus or a Big Maus. • Vehicles will now start losing HP at high altitude due to thin air. • Fixed a bug where artillery elevation behaved abnormally when aiming at targets that were too close or too far. • Fixed a bug where the Tracer prefix did not increase initial critical. • Fixed a bug where the explosion radius indicator could be covered by ice surfaces. • AI Valentine Gap Jumping Tanks will no longer jump around randomly.
