so i have been getting random invisible blocks and plants with my new modpack. i am in the process of migrating it from 1.6.4 to 1.7.10. below is a list of the mods i run in my personal PRIVATE modpack. i will continue to update the thread with a list of invisible blocks i find in my world, they are not all from one mod so i don't think this is a mod author issue as much as maybe mod incompatibility or forge or optifine. also here's a screenshot to explain what is happening as well.

Tinkers' Construct is officially incompatible with OptiFine (see the 5th question in the FAQ in the description thread for it), though I thought I had it working with OptiFine a few weeks ago - I don't know what changed or how it can affect blocks from other mods, but disabling OptiFine worked for me (with a very different modlist - the only ones I see in common are Tinker's Construct, Millenaire, and some of the NEI/Waila mods). You could try disabling one or the other temporarily to see if it helps.

thank you so much, switching the forge worked

Until someone ports this legendary mod I am leaving the minecraft scene. http://www.cosc.canterbury.ac.nz/greg.ewing/minecraft/mods/ArchitectureCraft/#mozTocId598776 I have watched too many legendary mods die and carpenters blocks sudden fallout out of mainstream made me cry. I realize the source is messy but some of the best mods from 1.6.4 and 1.7.10 were.
