After updating Arma Reforger Dedicated Server to version 1.8.0.10, a serious resource-loading issue appears whenever any addon is loaded on the server.

A completely vanilla dedicated server starts normally without these errors. However, as soon as even a single Workshop addon is enabled, the server begins producing a very large number of thermal profile resource errors during material finalization.

Typical errors include:
GetResourceObject @"{CC547D988287BF7C}system/thermal/thermalProfileDefault.conf"

RESOURCES (E): Failed to open

'system/thermal/thermalProfileDefault.conf' is not a valid thermal profile!

The same behavior also occurs with several other default thermal profiles, including the grass, terrain, tree crown and tree trunk profiles.

We have already verified that these thermal profile files are physically present in the original addons/core/data.pak, and the original core/resourceDatabase.rdb contains the expected resource paths and GUIDs.

The problem is reproducible with completely unrelated third-party Workshop addons, so it does not appear to be caused by one specific mod.
Multiple independent server owners have also reported/reproduced this behavior after the 1.8 update.

The server may eventually finish loading, but the amount of resource error spam is extremely large and significantly increases startup time and log size. It also makes it much harder for server administrators and mod developers to identify legitimate errors in their logs.
We would greatly appreciate if this issue could be investigated with high priority. Modded dedicated servers are very widely used in the Reforger community, and because the problem is reproducible simply by enabling an addon, it affects a potentially large number of community servers regardless of which mods they use.
