Subaquatic 1.2.1 block breaking / placing stuttering with specific mods installed.

[GrandeMalum]

Hello, dear developer. I've found a very strange incompatibility issue in your Minecraft mod Subaquatic 1.2.1. It can only be achieved by installing specific mods: assetmover v2.5, Fluidlogged API v2.2.7, OptiFine HD U G5, SereneSeasons v1.2.18, Subaquatic v1.2.1 and DramaticTrees v0.13.2. The mods can have default generated configs and options, and it doesn't matter if you have edited them, as the issue is still present. The problem is that the game gets microfreezing stuttering every time I place or destroy a block. This can especially be noticed inside of a forest biome. Not sure why though, but I believe it is because of the amount of objects that surround the player, as DramaticTrees (a fork of famous DynamicTrees mod) changes the way trees look. Uninstalling Subaquatic fully fixes the issue.

At first I was having a bit different issue, as I was playing with Nothirium v0.3.4, RenderLib v1.3.3 and mixinbooter v8.6 alongside previously mentioned mods. There were no stuttering, as probably Nothirium changed the way game performs and somehow fixed it, but on the other hand a different glitch occured. Placing blocks sometimes created invisible block with no texture, which could potentially work as an xray method for finding caves underground. It happens only for about a second, then the texture gets back there where the block was placed.

I did a very big research to find the exact mods which caused the issue in the first place, and I hope that it can help you with the development. I really want to make a modpack featuring Subaquatic. This mod is awesome and a musthave for any modern 1.12.2 modpack, but for now I'm not sure if it is a good idea to use it, as it can really ruin immersion with this issue.
