For starters the "Daves Vehicle Speed" mod. It's going to put a lot of strain on your CPU and hard drive for loading and accessing world data. Your systems inability to keep up is going to cause corruption in chunk and region data. No offense, but the 6th gen Intel CPU's are some of the worst. A 3rd gen clocks about 10% faster in the type of work the game client is doing. If your save data is not on an SSD, that's going to kick your ass even more.
Unless the mod actually reduces vehicle speeds. I wasn't able to locate it, but most mods like that are targeted towards making the vehicles faster.
The second is a trio. "No Heat Map From Sounds", "Clear Skies", and "Reasonably Large Stacks". Again, I was unable to locate these mods from any of the reputable sources. All could easily corrupt chunk data if improperly implemented though. Since I am unable to locate the mods, I am unable to verify what they are doing, and to what extent.
Add to this the fact that some of the mods you are using may not be updated for a19.5, and you've got another layer of possible issues.
