Update to version 1.041b!

Numerous things were wrong with the previous release, and hopefully some of this is addressed with this one also. Most notably the way things moved on the server deteriorated over time due to the version of Mirror I was using being buggy. The way I was controlling things was also inefficient, so the code to manage AI fish and birds has been overhauled.

Changes are as follows: - Unity updated to 2019.4.30f1 to fix shader issues present on the previous release. - Fish code replaced to be more universal, to use for more animal types in the future. - Fish added to more locations in all three maps, and they can wonder freely within a distance from their 'home'. - Fish can be seen from a greater distance. - Mirror networking package updated to latest version. - Enviro weather system updated to latest version.

Nothing ground-breaking I know, but hopefully it'll make the game more stable.

Any questions feel free to ask. Discord is probably the fastest for me to see.

Thanks for reading. :)
