Ruins of Thundertree Map with LOS enabled

[nicohinz1]

I have been playing around with the line of sight feature for FGU and everything seemed to work with it while on the Redbrand hideout map for Lost Mines of Pandelver. Last night I was trying to get my Ruin of Thunder tree map ready for my players and it seems like as soon as I enable the line of sight feature FGU crashes for some reason. I'm not sure if it is just on Ruins of Thunder tree or not but its starting to get pretty frustrating. Any insight would be helpful. Thank you.

Just a heads up I just tried it on Cragmaw Hideout map and it worked fine. Went back to Thundertree map and it crashed again.

I'm not seeing any issues and that map isn't the biggest in the module nor the most complex with the LoS.

Does this happen in a new campaign without any extensions? If it works in that perhaps an extension you are using is the issue or possibly you may need to revert changes on the map or module.
