Thanks for your report! I've just released version 2.3.1, which should fix this.

The new version should start to appear in the mod portal shortly.

Very appreciated. Although so after updating, it appears to freeze the game rather than cause a crash with a readable error.

Any chance you could send me your save file and any mods that aren't on the mod portal? I'm having trouble reproducing this, and I can't seem to find quality glassare and a couple other mods you listed

In the meanwhile, I've just uploaded version 2.3.2 which might have a fix?

Unfortunately so far the freeze still persists, and in fact the issue has been made worse. Removing the search light now causes the game to freeze.

Every mode I have was downloaded directly from the mod pod portal (with the exception of the three mods present by default, Elevated Rails, Quality, and Space Age.) Some of them may not show up if the Factorio Version option is not set to 2.0

Mediafire link to my current save file, with prepared scenario that causes the game to freeze: https://www.mediafire.com/file/z4lxiam5o7hklbl/space_age_first_go.zip/file

Thanks again, I'm really sorry for all the trouble. Sadly, I wasn't able to reproduce this issue, even with the scenario you provided.

I've posted a new update, version 2.3.3 which has another tentative fix, although I'm mostly grasping at straws trying to figure out what's causing the freeze on your side.
I also tried loading your save file in my game and re-saving over it. Maybe it will work for you with the migrations applied from my computer? https://drive.google.com/file/d/1ZF5XXyXxbYWSwhNVC2qV2mb-RMbTEmM5/view?usp=sharing

It is no problem. Using the save file you sent over with the latest updated version, it appears that the freeze is no longer present, although it does seem gun turrets boosted by the searchlight are unusually slow. Thank you.

The fire rate of boosted turrets is slowed down to help balance the mod.
Back when I was playing, it was very OP to have turrets use their full fire rate with such a range increase. Biter bases almost never had time to build up and send their counter attack forces because even just 4 gun turrets were killing a nest every few seconds, so there was no tension sniping a base clear in under a minute without any counter-play from the biters.

At some point I might make a setting to control it, but if you want the full fire speed back, just change sl-defines.lua from d.attackCooldownPenalty = 30 to d.attackCooldownPenalty = 1

There is some kind of error when overwriting the drawing lying in the book.
The book was not in the inventory, but in the book menu.

The SearchlightAssault mod (2.3.5) caused an unavoidable error. Please
report this error to the author of the mod.

Thanks for reporting this! I've just released a quick-fix with version 2.3.6.
(I don't have time to thoroughly test this until I get back from work, but hopefully it should at least stop that particular error)

The new version should start to appear in the mod portal shortly.
