Changing Game Build
Quick answer
Raising sv_enforceGameBuild loads a newer Rockstar DLC, and that DLC takes YMT slots your packs were already using. Your files did not change; the room they lived in got smaller.

Before you upgrade
- Read your current free slots and the target build's free slots on the build table.
- Count your YMTs, per gender.
- Subtract. If either gender would land at 0 or below, the upgrade will crash the server.
- Check the FXServer artifact the target build requires — see Builds & Artifacts.
Example: a server using 4 male and 4 female collections is comfortable on b3407 (6 free) and broken on b3889 (3 free). Nothing about the packs is wrong.
Confirm it was the build
Revert sv_enforceGameBuild to the last working value and restart. If the crash disappears with no other change, capacity is the cause.
This one test is faster and more conclusive than reading crash hashes, because hashes differ per build anyway.
Your options
| Option | Cost |
|---|---|
| Stay on the older build | Lose the new Rockstar content |
| Repack collections | Effort, and outfit IDs shift |
| Remove a clothing pack | Content loss |
| Move content to replace clothing | Overwrites vanilla items, more streaming load |
There is no convar that returns slots. increase_pool_size "YmtLimit" does not exist, and the contributor attempts to raise the underlying array ceiling remain unfinished.
Other causes after a build change
Not every post-upgrade problem is slot capacity:
- Outfit IDs moved. New DLC clothing shifts global drawable indexes. See Clothing IDs.
- Artifact too old. The build requires a newer FXServer than you run, and the server rejects the enforcement.
- Platform switch. Moving to Enhanced is not a build change — it is a different platform with different rules. See Legacy vs Enhanced.
- A script native changed. Unrelated to clothing.
What not to do
WARNING
Clearing cache after a build change
Cache does not hold YMT slots. The capacity was consumed by the DLC, on the client, before your resources loaded.
WARNING
Assuming the newest build is the best build
For servers with a lot of add-on clothing, newer is strictly worse: each DLC leaves fewer free collections. Build choice is a capacity decision.
