@k1lly0u - I am seeing this every time on reboot now.
for pretty much every single item
[12/24/2019 12:10:17 PM] Image failed to download! Error: HTTP/1.1 503 Service Unavailable - Image Name: rocket.launcher_1815384807 - Image URL: http://steamuserimages-a.akamaihd.net/ugc/779604484756635874/21A3B9E1DAF95A0C65A70DB7D253A2316B713167/ 
is just an example

Not sure how to fix this

I had the same issues when using Server Rewards /s. It says Image Fail to Download.
